5475cd780c ABI: sysfs-bus-soundwire-master: use wildcards on What definitions
An "N" upper letter is not a wildcard, nor can easily be identified
by script, specially since the USB sysfs define things like.
bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl

743e4636b7 ABI: sysfs-class-mic: use the right wildcards on What definitions

08981d29c3 ABI: sysfs-bus-rapidio: use wildcards on What definitions
While humans may be able to understand that something like:

	/sys/bus/rapidio/devices/nn:d:iiii

could actually mean:

	/sys/bus/rapidio/devices/00:e:0000

This is something that computers can't easily identify. As
get_abi.pl needs to convert it into a regex, change What: lines
to:

	/sys/bus/rapidio/devices/<nn>:<d>:<iiii>

Which is the commonly-used pattern on ABI files for wildcards.

6abaa83c73 f2fs-for-5.15-rc1
In this cycle, we've addressed some performance issues such as lock contention,
 misbehaving compress_cache, allowing extent_cache for compressed files, and new
 sysfs to adjust ra_size for fadvise. In order to diagnose the performance issues
 quickly, we also added an iostat which shows the IO latencies periodically. On
 the stability side, we've found two memory leakage cases in the error path in
 compression flow. And, we've also fixed various corner cases in fiemap, quota,
 checkpoint=disable, zstd, and so on.
 
 Enhancement:
  - avoid long checkpoint latency by releasing nat_tree_lock
  - collect and show iostats periodically
  - support extent_cache for compressed files
  - add a sysfs entry to manage ra_size given fadvise(POSIX_FADV_SEQUENTIAL)
  - report f2fs GC status via sysfs
  - add discard_unit=%s in mount option to handle zoned device
 
 Bug fix:
  - fix two memory leakages when an error happens in the compressed IO flow
  - fix commpress_cache to get the right LBA
  - fix fiemap to deal with compressed case correctly
  - fix wrong EIO returns due to SBI_NEED_FSCK
  - fix missing writes when enabling checkpoint back
  - fix quota deadlock
  - fix zstd level mount option
 
 In addition to the above major updates, we've cleaned up several code paths such
 as dio, unnecessary operations, debugfs/f2fs/status, sanity check, and typos.

20b51af15e mm/migrate: add sysfs interface to enable reclaim migration
Some method is obviously needed to enable reclaim-based migration.

Just like traditional autonuma, there will be some workloads that will
benefit like workloads with more "static" configurations where hot pages
stay hot and cold pages stay cold.  If pages come and go from the hot and
cold sets, the benefits of this approach will be more limited.

The benefits are truly workload-based and *not* hardware-based.  We do not
believe that there is a viable threshold where certain hardware
configurations should have this mechanism enabled while others do not.

To be conservative, earlier work defaulted to disable reclaim- based
migration and did not include a mechanism to enable it.  This proposes add
a new sysfs file

  /sys/kernel/mm/numa/demotion_enabled

as a method to enable it.

We are open to any alternative that allows end users to enable this
mechanism or disable it if workload harm is detected (just like
traditional autonuma).

Once this is enabled page demotion may move data to a NUMA node that does
not fall into the cpuset of the allocating process.  This could be
construed to violate the guarantees of cpusets.  However, since this is an
opt-in mechanism, the assumption is that anyone enabling it is content to
relax the guarantees.

a9c9a6f741 SCSI misc on 20210902
This series consists of the usual driver updates (ufs, qla2xxx,
 target, smartpqi, lpfc, mpt3sas).  The core change causing the most
 churn was replacing the command request field request with a macro,
 allowing us to offset map to it and remove the redundant field; the
 same was also done for the tag field.  The most impactful change is
 the final removal of scsi_ioctl, which has been deprecated for over a
 decade.

57c78a234e arm64 updates for 5.15:
- Support for 32-bit tasks on asymmetric AArch32 systems (on top of the
   scheduler changes merged via the tip tree).
 
 - More entry.S clean-ups and conversion to C.
 
 - MTE updates: allow a preferred tag checking mode to be set per CPU
   (the overhead of synchronous mode is smaller for some CPUs than
   others); optimisations for kernel entry/exit path; optionally disable
   MTE on the kernel command line.
 
 - Kselftest improvements for SVE and signal handling, PtrAuth.

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:

  core:
   - extract i915 eDP backlight into core
   - DP aux bus support

4cd67adc44 This tag contains habanalabs driver changes for v5.15:
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
   signals and signal them from within its workloads, while the driver
   performs the waiting. This allows finer granularity of pipelining
   between the different engines and resource utilization.
 
 - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
   on multiple command submissions (workloads) at the same time. This
   is an optimization for the user process so it won't need to call
   multiple times to the wait_for_cs ioctl.
 
 - Add new feature of "state dump", which can be triggered through new
   debugfs node. This is a similar concept to the kernel panic dump.
   This new mechanism retrieves information from the device in case
   one of the workloads that was sent by the user got stuck. This is
   very helpful for debugging the hang.
 
 - Add a new debugfs node to perform lookup of user pointers that are
   mapped to habana device's pmmu.
 
 - Fix to the tracking of user process when running inside a container.
 
 - Allow user to map more than 4GB of memory to the device MMU in single
   IOCTL call.
 
 - Minimize number of register reads done in GAUDI during user operation.
 
 - Allow user to retrieve the device's server type that the device is
   connected to.
 
 - Several fixes to the code of waiting on interrupts on behalf of the
   user.
 
 - Fixes and improvements to the hint mechanism in our VA allocation.
 
 - Update the firmware header files to the latest version while
   maintaining backward compatibility with older firmware versions.
 
 - Multiple fixes to various bugs.

ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:
  rtlwifi: use siocdevprivate") from the networking tree. When resolving
  the issue, I noted that the whole r8188eu rtw_android code is dead
  since commit ae7471cae0 ("staging: r8188eu: remove rtw_ioctl
  function").

  End result: the merge resolution was to throw all of that away,
  rather than do the mindless fixup to code that isn't actually
  reachable                                               - Linus ]

It is useful to have the ability to see which user address was pinned
to which physical address during the initial mapping. We already have
all that info stored, but no means to search this data (which may be
quite large).

26225bea1d iommu: Expose DMA domain strictness via sysfs
The sysfs interface for default domain types exists primarily so users
can choose the performance/security tradeoff relevant to their own
workload. As such, the choice between the policies for DMA domains fits
perfectly as an additional point on that scale - downgrading a
particular device from a strict default to non-strict may be enough to
let it reach the desired level of performance, while still retaining
more peace of mind than with a wide-open identity domain. Now that we've
abstracted non-strict mode as a distinct type of DMA domain, allow it to
be chosen through the user interface as well.

4f2946aa0c IMA: introduce a new policy option func=SETXATTR_CHECK
While users can restrict the accepted hash algorithms for the
security.ima xattr file signature when appraising said file, users
cannot restrict the algorithms that can be set on that attribute:
any algorithm built in the kernel is accepted on a write.

Define a new value for the ima policy option 'func' that restricts
globally the hash algorithms accepted when writing the security.ima
xattr.

When a policy contains a rule of the form
	appraise func=SETXATTR_CHECK appraise_algos=sha256,sha384,sha512
only values corresponding to one of these three digest algorithms
will be accepted for writing the security.ima xattr.  Attempting to
write the attribute using another algorithm (or "free-form" data)
will be denied with an audit log message.  In the absence of such a
policy rule, the default is still to only accept hash algorithms
built in the kernel (with all the limitations that entails).

583a80ae86 IMA: add a policy option to restrict xattr hash algorithms on appraisal
The kernel has the ability to restrict the set of hash algorithms it
accepts for the security.ima xattr when it appraises files.

Define a new IMA policy rule option "appraise_algos=", using the
mentioned mechanism to expose a user-toggable policy knob to opt-in
to that restriction and select the desired set of algorithms that
must be accepted.

When a policy rule uses the 'appraise_algos' option, appraisal of a
file referenced by that rule will now fail if the digest algorithm
employed to hash the file was not one of those explicitly listed in
the option.  In its absence, any hash algorithm compiled in the
kernel will be accepted.

For example, on a system where SELinux is properly deployed, the rule
	appraise func=BPRM_CHECK obj_type=iptables_exec_t \
		appraise_algos=sha256,sha384
will block the execution of iptables if the xattr security.ima of its
executables were not hashed with either sha256 or sha384.

b25d5a1cd1 ACPI: platform-profile: call sysfs_notify() from platform_profile_store()
Drivers like thinkpad_acpi and ideapad_laptop call the
platform_profile_notify() helper when the profile is changed by hardware
(the embedded-controller/EC) in response to an EC handled hotkey.

This allows userspace to monitor for such changes by polling for POLLPRI
on the platform_profile sysfs file. But the profile can also be changed
underneath a userspace program monitoring it by anonther userspace program
storing a new value.

Add a sysfs_notify() call to platform_profile_store(), so that userspace
programs monitoring for changes also get notified in this case.

Also update the documentation to document that POLLPRI polling can be
used to watch for changes.

Greg Kroah-Hartman
f805ef1ce5 First set of new IIO and counter device support, cleanups and features for 5.15
Usual mix of cleanups and new device support.
 
 Counter
 ======
 
 Cleanups and refactoring:
 * treewide
   - Ensure attempts to set invalid modes result in -EINVAL return.
   - Rename counter_count_function to counter_function as the middle count
     is redundant.
   - Standardize error returns when limits are exceeded.
 * 104-quad:
   - Document the lock.
   - Return an error if attempt to set the ceiling value in a mode that
     doesn't support it.
 * intel-qep
   - Drop unused bitops.h include
 
 IIO
 ===
 
 New device support
 * bma255
   - Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
     interrupt pin and not INT1. Patch set includes enabling use of INT2.
 * ingenic_adc
   - Add support for JZ4760 and similar and update bindings
   - Add support for JZ4760B and update bindings
 * rockchip_saradc
   - Add support for rk3568 ADC (separate channel array as more channels)
 * sgp40 gas sensor used to measure air quality
   - New driver including binding and ABI documentation.
 
 Bindings
 --------
 
 * Add missing bindings for many DACs where the binding was effectively
   implicit due to fallback probe methods in I2C and SPI.
   adi,ad5064
   adi,ad5360
   adi,ad5380
   adi,ad5421
   adi,ad5449
   adi,ad5504
   adi,ad5624r
   adi,ad5686 / adi,ad5696
   adi,ad5761
   adi,ad5764
   adi,ad5791
   adi,ad8801
   capella,cm3323 (also add explicit of_device_id table)
   microchip,mcp4922
 * bosch,bma255
   - Interrupt type in example was opposite of what the device expects.
     It's possible that a particular board had an inverter, but we
     definitely don't want the example to suggest this would be normal.
   - Add interrupt-names to allow for cases where only INT2 is connected.
   - Sort compatibles
   - Merge in very similar bosch,bma180 binding.
 
 New feature
 -----------
 
 * Devices only allowed to provide either extended_name or a label for given
   channel. If extend_name is used (generally discouraged but can't be
   removed as it would be a userspaece ABI change), then the label sysfs
   attribute will provide the extended_name. This allows some userspace
   parser simplications and hardening.
 * hid-sensors-pres
   - Add a timestamp channel (either from hardware, or locally filled).
 * vcnl3020
   - Add periodic sensor mode used to provide IIO events.
 
 Cleanups / minor fixes
 ----------------------
 
 * core/buffers
   - Avoid unnecessary zeroing of bitmaps that are immediately overwritten.
   - Move a sanity check earlier to simplify error path.
 * Quite a few cases of refactors to use devm_* for all of probe and drop
   remove
   - adjd_s311
   - adxl345
   - bma220
   - da280
   - dmard10
   - ds311
   - max5481
   - max5821
   - rfd77402
   - tcs3414
   - tmp006
 * ad5624r
   - Fix incorrect handling of a regulator that was preventing use of
     internal regulators.
 * adjd_s311
   - Allocate a buffer as part of iio_priv() structure as maximum size
     is small enough, no significant advantage in making it flexible sized.
 * bma220
   - Make handling of suspend and resume closer to the probe() wrt to the
     rather odd interface, that suspend mode is entered by reading a register.
 * ep93xx
   - Prepare clock before using (part of conversion to CCF)
 * fsl-imx25-gcq
   - Use local device pointer.
   - Adjust handling of platform_get_irq() to not check for 0 as an error.
     The function is documented as never returning it.
 * hid-sensors
   - Use devm_kmemdup() consistently across all drivers to simplify channel
     structure allocation management.
 * meson-saradc
   - Drop BL30 integration on G12A and newer SoCs as not used.
   - Whitespace fixes.
 * mpu6050
   - Add per device type startup times. This avoids an issue with having
     to dsicard initial data from gyroscopes when they were still stabilizing.
 * rfd77402
   - Change from passing private data, to passing i2c_client where only
     that is needed, reducing back and forth in pm functions.
 * si1145
   - Drop pointless continue
 * st-sensors
   - Cleanup of includes to remove unused and add missing headers that are used.
   - Use some devm functions to simplify probe() and remove() - gets us part way
     towards a fully device managed driver.
 * sx9310
   - Switch from of to generic properties to enable ACPI bindings.
 * vcnl3020
   - Add DMA safe buffer for bulk transfers.
   - Drop use of iio_claim_direct() in a driver that has no mode changes.
     A local lock is more appropriate.

Merge tag 'iio-for-5.15a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new IIO and counter device support, cleanups and features for 5.15

Usual mix of cleanups and new device support.

Counter
======

Cleanups and refactoring:
* treewide
  - Ensure attempts to set invalid modes result in -EINVAL return.
  - Rename counter_count_function to counter_function as the middle count
    is redundant.
  - Standardize error returns when limits are exceeded.
* 104-quad:
  - Document the lock.
  - Return an error if attempt to set the ceiling value in a mode that
    doesn't support it.
* intel-qep
  - Drop unused bitops.h include

IIO
===

New device support
* bma255
  - Add support fo the bosch,bmc156_accel which oddly only exposes the INT2
    interrupt pin and not INT1. Patch set includes enabling use of INT2.
* ingenic_adc
  - Add support for JZ4760 and similar and update bindings
  - Add support for JZ4760B and update bindings
* rockchip_saradc
  - Add support for rk3568 ADC (separate channel array as more channels)
* sgp40 gas sensor used to measure air quality
  - New driver including binding and ABI documentation.

Bindings
--------

* Add missing bindings for many DACs where the binding was effectively
  implicit due to fallback probe methods in I2C and SPI.
  adi,ad5064
  adi,ad5360
  adi,ad5380
  adi,ad5421
  adi,ad5449
  adi,ad5504
  adi,ad5624r
  adi,ad5686 / adi,ad5696
  adi,ad5761
  adi,ad5764
  adi,ad5791
  adi,ad8801
  capella,cm3323 (also add explicit of_device_id table)
  microchip,mcp4922
* bosch,bma255
  - Interrupt type in example was opposite of what the device expects.
    It's possible that a particular board had an inverter, but we
    definitely don't want the example to suggest this would be normal.
  - Add interrupt-names to allow for cases where only INT2 is connected.
  - Sort compatibles
  - Merge in very similar bosch,bma180 binding.

New feature
-----------

* Devices only allowed to provide either extended_name or a label for given
  channel. If extend_name is used (generally discouraged but can't be
  removed as it would be a userspaece ABI change), then the label sysfs
  attribute will provide the extended_name. This allows some userspace
  parser simplications and hardening.
* hid-sensors-pres
  - Add a timestamp channel (either from hardware, or locally filled).
* vcnl3020
  - Add periodic sensor mode used to provide IIO events.

Cleanups / minor fixes
----------------------

* core/buffers
  - Avoid unnecessary zeroing of bitmaps that are immediately overwritten.
  - Move a sanity check earlier to simplify error path.
* Quite a few cases of refactors to use devm_* for all of probe and drop
  remove
  - adjd_s311
  - adxl345
  - bma220
  - da280
  - dmard10
  - ds311
  - max5481
  - max5821
  - rfd77402
  - tcs3414
  - tmp006
* ad5624r
  - Fix incorrect handling of a regulator that was preventing use of
    internal regulators.
* adjd_s311
  - Allocate a buffer as part of iio_priv() structure as maximum size
    is small enough, no significant advantage in making it flexible sized.
* bma220
  - Make handling of suspend and resume closer to the probe() wrt to the
    rather odd interface, that suspend mode is entered by reading a register.
* ep93xx
  - Prepare clock before using (part of conversion to CCF)
* fsl-imx25-gcq
  - Use local device pointer.
  - Adjust handling of platform_get_irq() to not check for 0 as an error.
    The function is documented as never returning it.
* hid-sensors
  - Use devm_kmemdup() consistently across all drivers to simplify channel
    structure allocation management.
* meson-saradc
  - Drop BL30 integration on G12A and newer SoCs as not used.
  - Whitespace fixes.
* mpu6050
  - Add per device type startup times. This avoids an issue with having
    to dsicard initial data from gyroscopes when they were still stabilizing.
* rfd77402
  - Change from passing private data, to passing i2c_client where only
    that is needed, reducing back and forth in pm functions.
* si1145
  - Drop pointless continue
* st-sensors
  - Cleanup of includes to remove unused and add missing headers that are used.
  - Use some devm functions to simplify probe() and remove() - gets us part way
    towards a fully device managed driver.
* sx9310
  - Switch from of to generic properties to enable ACPI bindings.
* vcnl3020
  - Add DMA safe buffer for bulk transfers.
  - Drop use of iio_claim_direct() in a driver that has no mode changes.
    A local lock is more appropriate.

1081b9d971 iio: chemical: Add driver support for sgp40
sgp40 is a gas sensor used for measuring the air quality.

This driver is reading the raw resistance value which can be passed to
an userspace algorithm for further calculation.

The raw value is also used to calculate an estimated absolute voc index
in the range from 0 to 500. For this purpose the raw_mean value of the
resistance for which the index value is 250 might be set up as a
calibration step. This can be done with in_resistance_calibbias.

Compensation of relative humidity and temperature is supported and can
be used by writing to output values of out_humidityrelative_raw and
out_temp_raw.

There is a predecesor sensor type (sgp30) already existing. This driver
module was not extended because the new sensor is quite different in its
i2c telegrams.

0f920277dc misc: gehc-achc: new driver
General Electric Healthcare's PPD has a secondary processor from
NXP's Kinetis K20 series. That device has two SPI chip selects:

The main interface's behaviour depends on the loaded firmware
and is currently unused.

The secondary interface can be used to update the firmware using
EzPort protocol. This is implemented by this driver using the
kernel's firmware API. The firmware is being flashed into
non-volatile flash memory, so it is enough to flash it once
and not on every boot. Flashing will wear the flash memory
(it has a life time of at least 10k programming cycles). At
the same time only occasional FW updates are expected (like e.g.
a BIOS update). Thus the firmware update is triggered via sysfs
instead of doing it in the driver's probe routine like many
other drivers.

41d8a9333c scsi: ufs: ufshpb: Add HPB 2.0 support
Version 2.0 of HBP supports reads of varying sizes from 4KB to 1MB.

A read operation <= 32KB is supported as single HPB read. A read between
36KB and 1MB is supported by a combination of write buffer command and HPB
read command to deliver more PPN. The write buffer commands may not be
issued immediately due to busy tags. To use HPB read more aggressively, the
driver can requeue the write buffer command. The requeue threshold is
implemented as timeout and can be modified with requeue_timeout_ms entry in
sysfs.

f02bc9754a scsi: ufs: ufshpb: Introduce Host Performance Buffer feature
Implement Host Performance Buffer (HPB) initialization and add function
calls to UFS core driver.

NAND flash-based storage devices, including UFS, have mechanisms to
translate logical addresses of I/O requests to the corresponding physical
addresses of the flash storage.  In UFS, logical-to-physical-address (L2P)
map data, which is required to identify the physical address for the
requested I/Os, can only be partially stored in SRAM from NAND flash. Due
to this partial loading, accessing the flash address area, where the L2P
information for that address is not loaded in the SRAM, can result in
serious performance degradation.

The basic concept of HPB is to cache L2P mapping entries in host system
memory so that both physical block address (PBA) and logical block address
(LBA) can be delivered in HPB read command. The HPB read command allows to
read data faster than a regular read command in UFS since it provides the
physical address (HPB Entry) of the desired logical block in addition to
its logical address. The UFS device can access the physical block in NAND
directly without searching and uploading L2P mapping table. This improves
read performance because the NAND read operation for uploading L2P mapping
table is removed.

In HPB initialization, the host checks if the UFS device supports HPB
feature and retrieves related device capabilities. Then, HPB parameters are
configured in the device.

Total start-up time of popular applications was measured and the difference
observed between HPB being enabled and disabled. Popular applications are
12 game apps and 24 non-game apps. Each test cycle consists of running 36
applications in sequence. We repeated the cycle for observing performance
improvement by L2P mapping cache hit in HPB.

The following is the test environment:

 - kernel version: 4.4.0
 - RAM: 8GB
 - UFS 2.1 (64GB)

Results:

   +-------+----------+----------+-------+
   | cycle | baseline | with HPB | diff  |
   +-------+----------+----------+-------+
   | 1     | 272.4    | 264.9    | -7.5  |
   | 2     | 250.4    | 248.2    | -2.2  |
   | 3     | 226.2    | 215.6    | -10.6 |
   | 4     | 230.6    | 214.8    | -15.8 |
   | 5     | 232.0    | 218.1    | -13.9 |
   | 6     | 231.9    | 212.6    | -19.3 |
   +-------+----------+----------+-------+

We also measured HPB performance using iozone:

   $ iozone -r 4k -+n -i2 -ecI -t 16 -l 16 -u 16 -s $IO_RANGE/16 -F \
   mnt/tmp_1 mnt/tmp_2 mnt/tmp_3 mnt/tmp_4 mnt/tmp_5 mnt/tmp_6 mnt/tmp_7 \

0356e6283c usb: gadget: f_uac1: add volume and mute support
This adds bi-directional (host->device, device->host)
volume/mute support to the f_uac1 driver by adding
Feature Units and interrupt endpoint.

Currently only master channel is supported.

Volume and mute are configurable through configfs,
by default volume has -100..0 dB range with 1 dB step.

Similar to existing flexible endpoints configuration,
Feature Unit won't be added to the topology if both
mute and volume are not enabled, also interrupt endpoint
isn't added to the device if no feature unit is present

c715def515 dma-buf: Delete the DMA-BUF attachment sysfs statistics
The DMA-BUF attachment statistics form a subset of the DMA-BUF
sysfs statistics that recently merged to the drm-misc tree. They are not
UABI yet since they have not merged to the upstream Linux kernel.

Since there has been a reported a performance regression due to the
overhead of sysfs directory creation/teardown during
dma_buf_attach()/dma_buf_detach(), this patch deletes the DMA-BUF
attachment statistics from sysfs.

Fixes: bdb8d06dfe ("dmabuf: Add the capability to expose DMA-BUF stats in sysfs")

Added gc_reclaimed_segments and gc_segment_mode sysfs nodes.
1) "gc_reclaimed_segments" shows how many segments have been
reclaimed by GC during a specific GC mode.
2) "gc_segment_mode" is used to control for which gc mode
the "gc_reclaimed_segments" node shows.

227c4d507c f2fs-for-5.14-rc1
In this round, we've improved the compression support especially for Android
 such as allowing compression for mmap files, replacing the immutable bit with
 internal bit to prohibits data writes explicitly, and adding a mount option,
 "compress_cache", to improve random reads. And, we added "readonly" feature to
 compact the partition w/ compression enabled, which will be useful for Android
 RO partitions.
 
 Enhancement:
  - support compression for mmap file
  - use an f2fs flag instead of IMMUTABLE bit for compression
  - support RO feature w/ extent_cache
  - fully support swapfile with file pinning
  - improve atgc tunability
  - add nocompress extensions to unselect files for compression
 
 Bug fix:
  - fix false alaram on iget failure during GC
  - fix race condition on global pointers when there are multiple f2fs instances
  - add MODULE_SOFTDEP for initramfs
 
 As usual, we've also cleaned up some places for better code readability.
 (e.g., sysfs/feature, debugging messages, slab cache name, and docs)

Merge tag 'f2fs-for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've improved the compression support especially for
  Android such as allowing compression for mmap files, replacing the
  immutable bit with internal bit to prohibits data writes explicitly,
  and adding a mount option, "compress_cache", to improve random reads.
  And, we added "readonly" feature to compact the partition w/
  compression enabled, which will be useful for Android RO partitions.

  Enhancements:
   - support compression for mmap file
   - use an f2fs flag instead of IMMUTABLE bit for compression
   - support RO feature w/ extent_cache
   - fully support swapfile with file pinning
   - improve atgc tunability
   - add nocompress extensions to unselect files for compression

  Bug fixes:
   - fix false alaram on iget failure during GC
   - fix race condition on global pointers when there are multiple f2fs
     instances
   - add MODULE_SOFTDEP for initramfs

  As usual, we've also cleaned up some places for better code
  readability (e.g., sysfs/feature, debugging messages, slab cache
  name, and docs)"

a16d8644ba Staging / IIO driver patches for 5.14-rc1
Here is the big set of IIO and staging driver patches for 5.14-rc1.
 
 Loads of IIO driver updates and additions in here, the shortlog has the
 full details.
 
 For the staging side, we moved a few drivers out of staging, and deleted
 the kpc2000 drivers as the original developer asked us to because no one
 was working on them anymore.
 
 Also in here are loads of coding style cleanups due to different intern
 projects focusing on the staging tree to try to get experience doing
 kernel development.
 
 All of these have been in the linux-next tree for a while with no
 reported problems.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "This subsystem is still in the build-out phase as the bulk of the
  update is improvements to enumeration and fleshing out the device
  model. In terms of new features, more mailbox commands have been added
  to the allowed-list in support of persistent memory provisioning
  support targeting v5.15.

  The critical update from an enumeration perspective is support for the
  CXL Fixed Memory Window Structure that indicates to Linux which system
  physical address ranges decode to the CXL Host Bridges in the system.
  This allows the driver to detect which address ranges have been mapped
  by firmware and what address ranges are available for future hotplug.

  So, again, mostly skeleton this round, with more meat targeting v5.15.

  Summary:

   - Add support for the CXL Fixed Memory Window Structure, a recent
     extension of the ACPI CEDT (CXL Early Discovery Table)

   - Add infrastructure for component registers

   - Add HDM (Host-managed device memory) decoder definitions

   - Define a device model for an HDM decoder tree

   - Bridge CXL persistent memory capabilities to an NVDIMM bus /
     device-model

   - Switch to fine grained mapping of CXL MMIO registers to allow
     different drivers / system software to own individual register
     blocks

   - Enable media provisioning commands, and publish the label storage
     area size in sysfs

   - Miscellaneous cleanups and fixes"

8053f2d752 perf/x86/intel/uncore: Add alias PMU name
A perf PMU may have two PMU names. For example, Intel Sapphire Rapids
server supports the discovery mechanism. Without the platform-specific
support, an uncore PMU is named by a type ID plus a box ID, e.g.,
uncore_type_0_0, because the real name of the uncore PMU cannot be
retrieved from the discovery table. With the platform-specific support
later, perf has the mapping information from a type ID to a specific
uncore unit. Just like the previous platforms, the uncore PMU is named
by the real PMU name, e.g., uncore_cha_0. The user scripts which work
well with the old numeric name may not work anymore.

Add a new attribute "alias" to indicate the old numeric name. The
following userspace perf tool patch will handle both names. The user
scripts should work properly with the updated perf tool.

73f37068d5 ptp: support ptp physical/virtual clocks conversion
Support ptp physical/virtual clocks conversion via sysfs.
There will be a new attribute n_vclocks under ptp physical
clock sysfs.

- In default, the value is 0 meaning only ptp physical clock
  is in use.
- Setting the value can create corresponding number of ptp
  virtual clocks to use. But current physical clock is guaranteed
  to stay free running.
- Setting the value back to 0 can delete virtual clocks and back
  use physical clock again.

Another new attribute max_vclocks control the maximum number of
ptp vclocks.

 "Core:

   - BPF:
      - add syscall program type and libbpf support for generating
        instructions and bindings for in-kernel BPF loaders (BPF loaders
        for BPF), this is a stepping stone for signed BPF programs

ed78f56e12 powerpc/papr_scm: Make 'perf_stats' invisible if perf-stats unavailable
In case performance stats for an nvdimm are not available, reading the
'perf_stats' sysfs file returns an -ENOENT error. A better approach is
to make the 'perf_stats' file entirely invisible to indicate that
performance stats for an nvdimm are unavailable.

So this patch updates 'papr_nd_attribute_group' to add a 'is_visible'
callback implemented as newly introduced 'papr_nd_attribute_visible()'
that returns an appropriate mode in case performance stats aren't
supported in a given nvdimm.

Also the initialization of 'papr_scm_priv.stat_buffer_len' is moved
from papr_scm_nvdimm_init() to papr_scm_probe() so that it value is
available when 'papr_nd_attribute_visible()' is called during nvdimm
initialization.

Even though 'perf_stats' attribute is available since v5.9, there are
no known user-space tools/scripts that are dependent on presence of its
sysfs file. Hence I dont expect any user-space breakage with this
patch.

Let's create /sys/fs/f2fs/<disk>/feature_list/ to meet sysfs rule.

Note that there are three feature list entries:
1) /sys/fs/f2fs/features
  : shows runtime features supported by in-kernel f2fs along with Kconfig.
    - ref. F2FS_FEATURE_RO_ATTR()

2) /sys/fs/f2fs/$s_id/features <deprecated>
  : shows on-disk features enabled by mkfs.f2fs, used for old kernels. This
    won't add new feature anymore, and thus, users should check entries in 3)
    instead of this 2).

3) /sys/fs/f2fs/$s_id/feature_list
  : shows on-disk features enabled by mkfs.f2fs per instance, which follows
    sysfs entry rule where each entry should expose single value.
    This list covers old feature list provided by 2) and beyond. Therefore,
    please add new on-disk feature in this list only.

8af9fa37b8 platform/x86: dell-privacy: Add support for Dell hardware privacy
add support for Dell privacy driver for the Dell units equipped
hardware privacy design, which protect users privacy of audio and
camera from hardware level. Once the audio or camera privacy mode
activated, any applications will not get any audio or video stream
when user pressed ctrl+F4 hotkey, audio privacy mode will be
enabled, micmute led will be also changed accordingly
The micmute led is fully controlled by hardware & EC(embedded controller)
and camera mute hotkey is Ctrl+F9. Currently design only emits
SW_CAMERA_LENS_COVER event while the camera lens shutter will be
changed by EC & HW(hardware) control

*The flow is like this:
1) User presses key. HW does stuff with this key (timeout timer is started)
2) WMI event is emitted from BIOS to kernel
3) WMI event is received by dell-privacy
4) KEY_MICMUTE emitted from dell-privacy
5) Userland picks up key and modifies kcontrol for SW mute
6) Codec kernel driver catches and calls ledtrig_audio_set
7) dell-privacy notifies EC, the timeout is cancelled and the HW mute
   is activated. If the EC is not notified then the HW mic mute will
   activate when the timeout triggers, just a bit later than with the
   active ack.

b4e326165e USB: misc: Add onboard_usb_hub driver
The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.

Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.

Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).

Note: the current series only supports hubs connected directly to
a root hub (through xhci-plat), support for other configurations
could be added if needed.

bdb8d06dfe dmabuf: Add the capability to expose DMA-BUF stats in sysfs
Overview
========
The patch adds DMA-BUF statistics to /sys/kernel/dmabuf/buffers. It
allows statistics to be enabled for each DMA-BUF in sysfs by enabling
the config CONFIG_DMABUF_SYSFS_STATS.

The following stats will be exposed by the interface:

/sys/kernel/dmabuf/buffers/<inode_number>/exporter_name
/sys/kernel/dmabuf/buffers/<inode_number>/size
/sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/device
/sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/map_counter

The inode_number is unique for each DMA-BUF and was added earlier [1]
in order to allow userspace to track DMA-BUF usage across different
processes.

Use Cases
=========
The interface provides a way to gather DMA-BUF per-buffer statistics
from production devices. These statistics will be used to derive DMA-BUF
per-exporter stats and per-device usage stats for Android Bug reports.
The corresponding userspace changes can be found at [2].
Telemetry tools will also capture this information(along with other
memory metrics) periodically as well as on important events like a
foreground app kill (which might have been triggered by Low Memory
Killer). It will also contribute to provide a snapshot of the system
memory usage on other events such as OOM kills and Application Not
Responding events.

Background
==========
Currently, there are two existing interfaces that provide information
about DMA-BUFs.
1) /sys/kernel/debug/dma_buf/bufinfo
debugfs is however unsuitable to be mounted in production systems and
cannot be considered as an alternative to the sysfs interface being
proposed.
2) proc/<pid>/fdinfo/<fd>
The proc/<pid>/fdinfo/<fd> files expose information about DMA-BUF fds.
However, the existing procfs interfaces can only provide information
about the buffers for which processes hold fds or have the buffers
mmapped into their address space. Since the procfs interfaces alone
cannot provide a full picture of all DMA-BUFs in the system, there is
the need for an alternate interface to provide this information on
production systems.

The patch contains the following major improvements over v1:
1) Each attachment is represented by its own directory to allow creating
a symlink to the importing device and to also provide room for future
expansion.
2) The number of distinct mappings of each attachment is exposed in a
separate file.
3) The per-buffer statistics are now in /sys/kernel/dmabuf/buffers
inorder to make the interface expandable in future.

All of the improvements above are based on suggestions/feedback from
Daniel Vetter and Christian König.

A shell script that can be run on a classic Linux environment to read
out the DMA-BUF statistics can be found at [3](suggested by John
Stultz).

40ba17afdf cxl/acpi: Introduce cxl_decoder objects
A cxl_decoder is a child of a cxl_port. It represents a hardware decoder
configuration of an upstream port to one or more of its downstream
ports. The decoder is either represented in CXL standard HDM decoder
registers (see CXL 2.0 section 8.2.5.12 CXL HDM Decoder Capability
Structure), or it is a static decode configuration communicated by
platform firmware (see the CXL Early Discovery Table: Fixed Memory
Window Structure).

The firmware described and hardware described decoders differ slightly
leading to 2 different sub-types of decoders, cxl_decoder_root and
cxl_decoder_switch. At the root level the decode capabilities restrict
what can be mapped beneath them. Mid-level switch decoders are
configured for either acclerator (type-2) or memory-expander (type-3)
operation, but they are otherwise agnostic to the type of memory
(volatile vs persistent) being mapped.

Here is an example topology from a single-ported host-bridge environment
without CFMWS decodes enumerated.

7d4b5ca2e2 cxl/acpi: Add downstream port data to cxl_port instances
In preparation for infrastructure that enumerates and configures the CXL
decode mechanism of an upstream port to its downstream ports, add a
representation of a CXL downstream port.

On ACPI systems the top-most logical downstream ports in the hierarchy
are the host bridges (ACPI0016 devices) that decode the memory windows
described by the CXL Early Discovery Table Fixed Memory Window
Structures (CEDT.CFMWS).

4812be97c0 cxl/acpi: Introduce the root of a cxl_port topology
While CXL builds upon the PCI software model for enumeration and
endpoint control, a static platform component is required to bootstrap
the CXL memory layout. Similar to how ACPI identifies root-level PCI
memory resources, ACPI data enumerates the address space and interleave
configuration for CXL Memory.

In addition to identifying host bridges, ACPI is responsible for
enumerating the CXL memory space that can be addressed by downstream
decoders. This is similar to the requirement for ACPI to publish
resources via the _CRS method for PCI host bridges. Specifically, ACPI
publishes a table, CXL Early Discovery Table (CEDT), which includes a
list of CXL Memory resources, CXL Fixed Memory Window Structures
(CFMWS).

For now, introduce the core infrastructure for a cxl_port hierarchy
starting with a root level anchor represented by the ACPI0017 device.

Follow on changes model support for the configurable decode capabilities
of cxl_port instances, i.e. CXL switch support.

e89bb42883 usb: gadget: u_audio: add real feedback implementation
This adds interface between userspace and feedback endpoint to report real
feedback frequency to the Host.

Current implementation adds new userspace interface ALSA mixer control
"Capture Pitch 1000000" (similar to aloop driver's "PCM Rate Shift 100000"
mixer control)

Value in PPM is chosen to have correction value agnostic of the actual HW
rate, which the application is not necessarily dealing with, while still
retaining a good enough precision to allow smooth clock correction on the
playback side, if necessary.

Similar to sound/usb/endpoint.c, a slow down is allowed up to 25%. This
has no impact on the required bandwidth. Speedup correction has an impact
on the bandwidth reserved for the isochronous endpoint. The default
allowed speedup is 500ppm. This seems to be more than enough but, if
necessary, this is configurable through a module parameter. The reserved
bandwidth is rounded up to the next packet size.

Usage of this new control is easy to implement in existing userspace tools
like alsaloop from alsa-utils.

can consume audio samples at any rate (for example,
on the Gadget side someone records audio directly to

external DAC as soon as they arrive), UAC2 spec

This patch deprecates the usage of EVM_ALLOW_METADATA_WRITES, as it is no
longer necessary. All the issues that prevent the usage of EVM portable
signatures just with a public key loaded have been solved.

This flag will remain available for a short time to ensure that users are
able to use EVM without it.

1cbf680f76 thunderbolt: Allow router NVM authenticate separately
It may be useful if the actual NVM authentication can be delayed to be
run later, for instance when the user logs out. For this reason add a
new NVM operation (AUHENTICATE_ONLY) that just triggers the authentication
procedure over whatever was written to the NVM storage.

This is not supported with Thunderbolt 1-3 devices, though.

3fb10ea4ce thunderbolt: Add support for retimer NVM upgrade when there is no link
With help from platform firmware (ACPI) it is possible to power on
retimers even when there is no USB4 link (e.g nothing is connected to
the USB4 ports). This allows us to bring the USB4 sideband up so that we
can access retimers and upgrade their NVM firmware.

If the platform has support for this, we expose two additional
attributes under USB4 ports: offline and rescan. These can be used to
bring the port offline, rescan for the retimers and put the port online
again. The retimer NVM upgrade itself works the same way than with cable
connected.

The description of those vars produce this warning:
  Documentation/ABI/testing/sysfs-bus-iio:799: WARNING: Inline emphasis start-string without end-string.

Due to an asterisk, which is the markup for emphasis. One possible
fix would be to use ``*_timeout`` to avoid it, but looking at
the descriptions of other fields in this file, a common pattern
is to refer to "these" when talking about the API calls that
are described.

So, change the text in order to preserve the meaning while
avoiding the need of using an asterisk there.

c037b6c818 PCI: Add sysfs "removable" attribute
A PCI device is "external_facing" if it's a Root Port with the ACPI
"ExternalFacingPort" property or if it has the DT "external-facing"
property.  We consider everything downstream from such a device to
be removable by user.

We're mainly concerned with consumer platforms with user accessible
Thunderbolt ports that are vulnerable to DMA attacks, and we expect those
ports to be identified by firmware as "ExternalFacingPort". Devices in
traditional hotplug slots can technically be removed, but the expectation
is that unless the port is marked with "ExternalFacingPort", such devices
are less accessible to user / may not be removed by end user, and thus not
exposed as "removable" to userspace.

This can be used to implement userspace policies tailored for
user removable devices. Eg usage:
https://chromium-review.googlesource.com/c/chromiumos/platform2/+/2591812
https://chromium-review.googlesource.com/c/chromiumos/platform2/+/2795038
(code uses such an attribute to remove external PCI devices or disable
features on them as needed by the policy desired)

70f400d4d9 driver core: Move the "removable" attribute from USB to core
Move the "removable" attribute from USB to core in order to allow it to be
supported by other subsystem / buses. Individual buses that want to support
this attribute can populate the removable property of the device while
enumerating it with the 3 possible values -
 - "unknown"
 - "fixed"
 - "removable"
Leaving the field unchanged (i.e. "not supported") would mean that the
attribute would not show up in sysfs for that device. The UAPI (location,
symantics etc) for the attribute remains unchanged.

Move the "removable" attribute from USB to the device core so it can be
used by other subsystems / buses.

By default, devices do not have a "removable" attribute in sysfs.

If a subsystem or bus driver wants to support a "removable" attribute, it
should call device_set_removable() before calling device_register() or
device_add(), e.g.:

    device_set_removable(dev, DEVICE_REMOVABLE);
    device_register(dev);

The possible values and the resulting sysfs attribute contents are:

    DEVICE_REMOVABLE_UNKNOWN  ->  "unknown"
    DEVICE_REMOVABLE          ->  "removable"
    DEVICE_FIXED              ->  "fixed"

Convert the USB "removable" attribute to use this new device core
functionality.  There should be no user-visible change in the location or
semantics of attribute for USB devices.

9acc89d31f evm: Refuse EVM_ALLOW_METADATA_WRITES only if an HMAC key is loaded
EVM_ALLOW_METADATA_WRITES is an EVM initialization flag that can be set to
temporarily disable metadata verification until all xattrs/attrs necessary
to verify an EVM portable signature are copied to the file. This flag is
cleared when EVM is initialized with an HMAC key, to avoid that the HMAC is
calculated on unverified xattrs/attrs.

Currently EVM unnecessarily denies setting this flag if EVM is initialized
with a public key, which is not a concern as it cannot be used to trust
xattrs/attrs updates. This patch removes this limitation.

Added a sysfs entry to support writing to the offset register on page1.
This register is used to calibrate the chip canceling offset errors in the
current ADC. This means that, over time, reading the IAD register will not
return the correct current measurement, it will have an offset. Writing to
the offset register if the two's complement of the current register while
passing zero current to the load will calibrate the measurements. This
change was tested on real hardware and it was able to calibrate the chip
correctly.

While the previous ABI will be kept forever, the best is
for applications to use the 5.11+ ABI. So, move the

As a side note, this was particular bit of ABI occurs in other drivers

This patch attempts to make a best effort of adding it to the main docs but
retaining enough information. Both of these drivers probably need

those should be in the main documentation, not under Documentation/ABI.

After seeing some users have subscription management trouble, more spam
than other Linux development lists, and considering some of the benefits
of kernel.org hosted lists, nvdimm and persistent memory development is
moving to nvdimm@lists.linux.dev.

The old list will remain up until v5.14-rc1 and shutdown thereafter.

43ca106fa8 mm: cma: support sysfs
Since CMA is getting used more widely, it's more important to keep
monitoring CMA statistics for system health since it's directly related to
user experience.

This patch introduces sysfs statistics for CMA, in order to provide some
basic monitoring of the CMA allocator.

 * the number of CMA page successful allocations
 * the number of CMA page allocation failures

These two values allow the user to calcuate the allocation
failure rate for each CMA area.

e.g.)
  /sys/kernel/mm/cma/WIFI/alloc_pages_[success|fail]
  /sys/kernel/mm/cma/SENSOR/alloc_pages_[success|fail]
  /sys/kernel/mm/cma/BLUETOOTH/alloc_pages_[success|fail]

The cma_stat was intentionally allocated by dynamic allocation
to harmonize with kobject lifetime management.

d0195c7d7a f2fs-for-5.13-rc1
In this round, we added a new mount option, "checkpoint_merge", which introduces
 a kernel thread dealing with the f2fs checkpoints. Once we start to manage the
 IO priority along with blk-cgroup, the checkpoint operation can be processed in
 a lower priority under the process context. Since the checkpoint holds all the
 filesystem operations, we give a higher priority to the checkpoint thread all
 the time.
 
 Enhancement:
 - introduce gc_merge mount option to introduce a checkpoint thread
 - improve to run discard thread efficiently
 - allow modular compression algorithms
 - expose # of overprivision segments to sysfs
 - expose runtime compression stat to sysfs
 
 Bug fix:
 - fix OOB memory access by the node id lookup
 - avoid touching checkpointed data in the checkpoint-disabled mode
 - fix the resizing flow to avoid kernel panic and race conditions
 - fix block allocation issues on pinned files
 - address some swapfile issues
 - fix hugtask problem and kernel panic during atomic write operations
 - don't start checkpoint thread in RO
 
 And, we've cleaned up some kernel coding style and build warnings. In addition,
 we fixed some minor race conditions and error handling routines.

Linus Torvalds
9d31d23389 Networking changes for 5.13.
Core:
 
  - bpf:
 	- allow bpf programs calling kernel functions (initially to
 	  reuse TCP congestion control implementations)
 	- enable task local storage for tracing programs - remove the
 	  need to store per-task state in hash maps, and allow tracing
 	  programs access to task local storage previously added for
 	  BPF_LSM
 	- add bpf_for_each_map_elem() helper, allowing programs to
 	  walk all map elements in a more robust and easier to verify
 	  fashion
 	- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
 	  redirection
 	- lpm: add support for batched ops in LPM trie
 	- add BTF_KIND_FLOAT support - mostly to allow use of BTF
 	  on s390 which has floats in its headers files
 	- improve BPF syscall documentation and extend the use of kdoc
 	  parsing scripts we already employ for bpf-helpers
 	- libbpf, bpftool: support static linking of BPF ELF files
 	- improve support for encapsulation of L2 packets
 
  - xdp: restructure redirect actions to avoid a runtime lookup,
 	improving performance by 4-8% in microbenchmarks
 
  - xsk: build skb by page (aka generic zerocopy xmit) - improve
 	performance of software AF_XDP path by 33% for devices
 	which don't need headers in the linear skb part (e.g. virtio)
 
  - nexthop: resilient next-hop groups - improve path stability
 	on next-hops group changes (incl. offload for mlxsw)
 
  - ipv6: segment routing: add support for IPv4 decapsulation
 
  - icmp: add support for RFC 8335 extended PROBE messages
 
  - inet: use bigger hash table for IP ID generation
 
  - tcp: deal better with delayed TX completions - make sure we don't
 	give up on fast TCP retransmissions only because driver is
 	slow in reporting that it completed transmitting the original
 
  - tcp: reorder tcp_congestion_ops for better cache locality
 
  - mptcp:
 	- add sockopt support for common TCP options
 	- add support for common TCP msg flags
 	- include multiple address ids in RM_ADDR
 	- add reset option support for resetting one subflow
 
  - udp: GRO L4 improvements - improve 'forward' / 'frag_list'
 	co-existence with UDP tunnel GRO, allowing the first to take
 	place correctly	even for encapsulated UDP traffic
 
  - micro-optimize dev_gro_receive() and flow dissection, avoid
 	retpoline overhead on VLAN and TEB GRO
 
  - use less memory for sysctls, add a new sysctl type, to allow using
 	u8 instead of "int" and "long" and shrink networking sysctls
 
  - veth: allow GRO without XDP - this allows aggregating UDP
 	packets before handing them off to routing, bridge, OvS, etc.
 
  - allow specifing ifindex when device is moved to another namespace
 
  - netfilter:
 	- nft_socket: add support for cgroupsv2
 	- nftables: add catch-all set element - special element used
 	  to define a default action in case normal lookup missed
 	- use net_generic infra in many modules to avoid allocating
 	  per-ns memory unnecessarily
 
  - xps: improve the xps handling to avoid potential out-of-bound
 	accesses and use-after-free when XPS change race with other
 	re-configuration under traffic
 
  - add a config knob to turn off per-cpu netdev refcnt to catch
 	underflows in testing
 
 Device APIs:
 
  - add WWAN subsystem to organize the WWAN interfaces better and
    hopefully start driving towards more unified and vendor-
    -independent APIs
 
  - ethtool:
 	- add interface for reading IEEE MIB stats (incl. mlx5 and
 	  bnxt support)
 	- allow network drivers to dump arbitrary SFP EEPROM data,
 	  current offset+length API was a poor fit for modern SFP
 	  which define EEPROM in terms of pages (incl. mlx5 support)
 
  - act_police, flow_offload: add support for packet-per-second
 	policing (incl. offload for nfp)
 
  - psample: add additional metadata attributes like transit delay
 	for packets sampled from switch HW (and corresponding egress
 	and policy-based sampling in the mlxsw driver)
 
  - dsa: improve support for sandwiched LAGs with bridge and DSA
 
  - netfilter:
 	- flowtable: use direct xmit in topologies with IP
 	  forwarding, bridging, vlans etc.
 	- nftables: counter hardware offload support

 	11-port Ethernet switch with 8x 1-Gigabit Ethernet
 	and 3x 10-Gigabit interfaces.
 
  - dsa: support for legacy Broadcom tags used on BCM5325, BCM5365
 	and BCM63xx switches
 
  - Microchip KSZ8863 and KSZ8873; 3x 10/100Mbps Ethernet switches
 
  - ath11k: support for QCN9074 a 802.11ax device
 
  - Bluetooth: Broadcom BCM4330 and BMC4334
 
  - phy: Marvell 88X2222 transceiver support
 
  - mdio: add BCM6368 MDIO mux bus controller
 
  - r8152: support RTL8153 and RTL8156 (USB Ethernet) chips
 
  - mana: driver for Microsoft Azure Network Adapter (MANA)
 
  - Actions Semi Owl Ethernet MAC

6daa755f81 s390 updates for 5.13 merge window
- fix buffer size for in-kernel disassembler for ebpf programs.
 
 - fix two memory leaks in zcrypt driver.
 
 - expose PCI device UID as index, including an indicator if the uid is
   unique.
 
 - remove some oprofile leftovers.
 
 - improve stack unwinder tests.
 
 - don't use gcc atomic builtins anymore, just like all other
   architectures. Even though I'm sure the current code is ok, I
   totally dislike that s390 is the only architecture being special
   here; especially considering that there was a lengthly discussion
   about this topic and the outcome was not to use the builtins.
   Therefore open-code atomic ops again with inline assembly and switch
   to gcc builtins as soon as other architectures are doing.
 
 - couple of other changes to atomic and cmpxchg, and use
   atomic-instrumented.h for KASAN.
 
 - separate zbus creation, registration, and scanning in our PCI code
   which allows for cleaner and easier handling.
 
 - a rather large change to the vfio-ap code to fix circular locking
   dependencies when updating crypto masks.
 
 - move QAOB handling from qdio layer down to drivers.
 
 - add CRW inject facility to common I/O layer. This adds debugs files
   which allow to generate artificial events from user space for
   testing purposes.
 
 - increase SCLP console line length from 80 to 320 characters to avoid
   odd wrapped lines.
 
 - add protected virtualization guest and host indication files, which
   indicate either that a guest is running in pv mode or if the
   hypervisor is capable of starting pv guests.

8900d92fd6 Staging/IIO driver updates for 5.13-rc1
Here is the big set of staging and IIO driver updates for 5.13-rc1.
 
 Lots of little churn in here, and some larger churn as well.  Major
 things are:
 	- removal of wimax drivers, no one has this hardware anymore for
 	  this failed "experiment".
 	- removal of the Google gasket driver, turns out no one wanted
 	  to maintain it or cares about it anymore, so they asked for it
 	  to be removed.
 	- comedi finally moves out of the staging directory into
 	  drivers/comedi/  This is one of the oldest kernel subsystems
 	  around, being created in the 2.0 kernel days, and was one of
 	  the first things added to drivers/staging/ when that was
 	  created over 15 years ago.  It should have been moved out of
 	  staging a long time ago, it's well maintained and used by
 	  loads of different devices in the real world every day.  Nice
 	  to see this finally happen.
 	- so many tiny coding style cleanups it's not funny.  Perfect
 	  storm of at least 2 different intern project application
 	  deadlines combined to provide a huge number of new
 	  contributions in this area from people learning how to do
 	  kernel development.  Great job to everyone involved here.
 
 There's also the normal updates for IIO drivers with new IIO drivers and
 updates all over that subsystem.
 
 All of these have been in linux-next for a while with no reported
 issues.

81dd4d4d61 dmaengine: idxd: Add IDXD performance monitor support
Implement the IDXD performance monitor capability (named 'perfmon' in
the DSA (Data Streaming Accelerator) spec [1]), which supports the
collection of information about key events occurring during DSA and
IAX (Intel Analytics Accelerator) device execution, to assist in
performance tuning and debugging.

The idxd perfmon support is implemented as part of the IDXD driver and
interfaces with the Linux perf framework.  It has several features in
common with the existing uncore pmu support:

  - it does not support sampling
  - does not support per-thread counting

However it also has some unique features not present in the core and
uncore support:

  - all general-purpose counters are identical, thus no event constraints
  - operation is always system-wide

While the core perf subsystem assumes that all counters are by default
per-cpu, the uncore pmus are socket-scoped and use a cpu mask to
restrict counting to one cpu from each socket.  IDXD counters use a
similar strategy but expand the scope even further; since IDXD
counters are system-wide and can be read from any cpu, the IDXD perf
driver picks a single cpu to do the work (with cpu hotplug notifiers
to choose a different cpu if the chosen one is taken off-line).

More specifically, the perf userspace tool by default opens a counter
for each cpu for an event.  However, if it finds a cpumask file
associated with the pmu under sysfs, as is the case with the uncore
pmus, it will open counters only on the cpus specified by the cpumask.
Since perfmon only needs to open a single counter per event for a
given IDXD device, the perfmon driver will create a sysfs cpumask file
for the device and insert the first cpu of the system into it.  When a
user uses perf to open an event, perf will open a single counter on
the cpu specified by the cpu mask.  This amounts to the default
system-wide rather than per-cpu counting mentioned previously for
perfmon pmu events.  In order to keep the cpu mask up-to-date, the
driver implements cpu hotplug support for multiple devices, as IDXD
usually enumerates and registers more than one idxd device.

The perfmon driver implements basic perfmon hardware capability
discovery and configuration, and is initialized by the IDXD driver's
probe function.  During initialization, the driver retrieves the total
number of supported performance counters, the pmu ID, and the device
type from idxd device, and registers itself under the Linux perf
framework.

The perf userspace tool can be used to monitor single or multiple
events depending on the given configuration, as well as event groups,
which are also supported by the perfmon driver.  The user configures
events using the perf tool command-line interface by specifying the
event and corresponding event category, along with an optional set of
filters that can be used to restrict counting to specific work queues,
traffic classes, page and transfer sizes, and engines (See [1] for
specifics).

With the configuration specified by the user, the perf tool issues a
system call passing that information to the kernel, which uses it to
initialize the specified event(s).  The event(s) are opened and
started, and following termination of the perf command, they're
stopped.  At that point, the perfmon driver will read the latest count
for the event(s), calculate the difference between the latest counter
values and previously tracked counter values, and display the final
incremental count as the event count for the cycle.  An overflow
handler registered on the IDXD irq path is used to account for counter
overflows, which are signaled by an overflow interrupt.

Below are a couple of examples of perf usage for monitoring DSA events.

The following monitors all events in the 'engine' category.  Becuuse
no filters are specified, this captures all engine events for the
workload, which in this case is 19 iterations of the work generated by
the kernel dmatest module.

Details describing the events can be found in Appendix D of [1],
Performance Monitoring Events, but briefly they are:

  event 0x1:  total input data processed, in 32-byte units
  event 0x2:  total data written, in 32-byte units
  event 0x4:  number of work descriptors that read the source
  event 0x8:  number of work descriptors that write the destination
  event 0x10: number of work descriptors dispatched from batch descriptors
  event 0x20: number of work descriptors dispatched from work queues

 # perf stat -e dsa0/event=0x1,event_category=0x1/,
                dsa0/event=0x2,event_category=0x1/,
		dsa0/event=0x4,event_category=0x1/,
		dsa0/event=0x8,event_category=0x1/,
		dsa0/event=0x10,event_category=0x1/,
		dsa0/event=0x20,event_category=0x1/
		  modprobe dmatest channel=dma0chan0 timeout=2000
		  iterations=19 run=1 wait=1

     Performance counter stats for 'system wide':

                 5,332      dsa0/event=0x1,event_category=0x1/
                 5,327      dsa0/event=0x2,event_category=0x1/
                    19      dsa0/event=0x4,event_category=0x1/
                    19      dsa0/event=0x8,event_category=0x1/
                     0      dsa0/event=0x10,event_category=0x1/
                    19      dsa0/event=0x20,event_category=0x1/

          21.977436186 seconds time elapsed

The command below illustrates filter usage with a simple example.  It
specifies that MEM_MOVE operations should be counted for the DSA
device dsa0 (event 0x8 corresponds to the EV_MEM_MOVE event - Number
of Memory Move Descriptors, which is part of event category 0x3 -
Operations. The detailed category and event IDs are available in
Appendix D, Performance Monitoring Events, of [1]).  In addition to
the event and event category, a number of filters are also specified
(the detailed filter values are available in Chapter 6.4 (Filter
Support) of [1]), which will restrict counting to only those events
that meet all of the filter criteria.  In this case, the filters
specify that only MEM_MOVE operations that are serviced by work queue
wq0 and specifically engine number engine0 and traffic class tc0
having sizes between 0 and 4k and page size of between 0 and 1G result
in a counter hit; anything else will be filtered out and not appear in
the final count.  Note that filters are optional - any filter not
specified is assumed to be all ones and will pass anything.

 # perf stat -e dsa0/filter_wq=0x1,filter_tc=0x1,filter_sz=0x7,
                filter_eng=0x1,event=0x8,event_category=0x3/
		  modprobe dmatest channel=dma0chan0 timeout=2000
		  iterations=19 run=1 wait=1

     Performance counter stats for 'system wide':

       19      dsa0/filter_wq=0x1,filter_tc=0x1,filter_sz=0x7,
               filter_eng=0x1,event=0x8,event_category=0x3/

          21.865914091 seconds time elapsed

The output above reflects that the unspecified workload resulted in
the counting of 19 MEM_MOVE operation events that met the filter
criteria.

81bbf03905 s390/pci: expose a PCI device's UID as its index
On s390 each PCI device has a user-defined ID (UID) exposed under
/sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI
device's primary index and to match the device within Linux to the
device configured in the hypervisor. To serve as a primary identifier
the UID must be unique within the Linux instance, this is guaranteed by
the platform if and only if the UID Uniqueness Checking flag is set
within the CLP List PCI Functions response.

In this sense the UID serves an analogous function as the SMBIOS
instance number or ACPI index exposed as the "index" respectively
"acpi_index" device attributes and used by e.g. systemd to set interface
names. As s390 does not use and will likely never use ACPI nor SMBIOS
there is no conflict and we can just expose the UID under the "index"
attribute whenever UID Uniqueness Checking is active and get systemd's
interface naming support for free.

ee7abc105e platform/x86: intel_pmc_core: export platform global reset bits via etr3 sysfs file
During PCH (platform/board) manufacturing process a global platform
reset has to be induced in order for the configuration changes take
the effect upon following platform reset. This is an internal platform
state and is not intended to be used in the regular platform resets.
The setting is exposed via ETR3 (Extended Test Mode Register 3).
After the manufacturing process is completed the register cannot be
written anymore and is hardware locked.
This setting was commonly done by accessing PMC registers via /dev/mem
but due to security concerns /dev/mem access is much more restricted,
hence the reason for exposing this setting via the dedicated sysfs
interface.
To prevent post manufacturing abuse the register is protected
by hardware locking and the file is set to read-only mode via is_visible
handler.

The register in MMIO space is defined for Cannon Lake and newer PCHs.

639781dcab habanalabs/gaudi: add debugfs to DMA from the device
When trying to debug program, the user often needs to
dump large parts of the device's DRAM, which can reach to tens of GBs.
Because reading from the device's internal memory through the PCI BAR
is extremely slow, the debug can take hours.

Instead, we can provide the user to copy data through one of the DMA
engines. This will make the operation much faster.

Currently, only GAUDI is supported.

In GAUDI, we need to find a PCI DMA engine that is IDLE and set the
DMA as secured to be able to bypass our MMU as we currently don't
map the temporary buffer to the MMU.

Example bash one-line to dump entire HBM to file (~2 minutes):

for (( i=0x0; i < 0x800000000; i+=0x8000000 )); do \
printf '0x%x\n' $i | sudo tee /sys/kernel/debug/habanalabs/hl0/addr ; \
echo 0x8000000 | sudo tee /sys/kernel/debug/habanalabs/hl0/dma_size ; \
sudo cat /sys/kernel/debug/habanalabs/hl0/data_dma >> hbm.txt ; done

167f77f7d0 power: supply: Add battery driver for Surface Aggregator Module
On newer Microsoft Surface models (specifically 7th-generation, i.e.
Surface Pro 7, Surface Book 3, Surface Laptop 3, and Surface Laptop Go),
battery and AC status/information is no longer handled via standard ACPI
devices, but instead directly via the Surface System Aggregator Module
(SSAM), i.e. the embedded controller on those devices.

While on previous generation models, battery status is also handled via
SSAM, an ACPI shim was present to translate the standard ACPI battery
interface to SSAM requests. The SSAM interface itself, which is modeled
closely after the ACPI interface, has not changed.

This commit introduces a new SSAM client device driver to support
battery status/information via the aforementioned interface on said
Surface models. It is in parts based on the standard ACPI battery
driver.

c3d5c2d96d PCI/IOV: Add sysfs MSI-X vector assignment interface
A typical cloud provider SR-IOV use case is to create many VFs for use by
guest VMs. The VFs may not be assigned to a VM until a customer requests a
VM of a certain size, e.g., number of CPUs. A VF may need MSI-X vectors
proportional to the number of CPUs in the VM, but there is no standard way
to change the number of MSI-X vectors supported by a VF.

Some Mellanox ConnectX devices support dynamic assignment of MSI-X vectors
to SR-IOV VFs. This can be done by the PF driver after VFs are enabled,
and it can be done without affecting VFs that are already in use. The
hardware supports a limited pool of MSI-X vectors that can be assigned to
the PF or to individual VFs.  This is device-specific behavior that
requires support in the PF driver.

Add a read-only "sriov_vf_total_msix" sysfs file for the PF and a writable
"sriov_vf_msix_count" file for each VF. Management software may use these
to learn how many MSI-X vectors are available and to dynamically assign
them to VFs before the VFs are passed through to a VM.

If the PF driver implements the ->sriov_get_vf_total_msix() callback,
"sriov_vf_total_msix" contains the total number of MSI-X vectors available
for distribution among VFs.

If no driver is bound to the VF, writing "N" to "sriov_vf_msix_count" uses
the PF driver ->sriov_set_msix_vec_count() callback to assign "N" MSI-X
vectors to the VF.  When a VF driver subsequently reads the MSI-X Message
Control register, it will see the new Table Size "N".

9c15db92a8 1st set of IIO/counter device support, features and cleanup in the 5.13 cycle
Big set in here from Alexandru Ardelean enabling multiple buffer support.
 This includes providing a new directory per buffer that combines
 what was previously in buffer/ and scan_elements/. Old interfaces still
 in place for compatiblity.
 
 Note immuatable branch for scmi patches to allow for some significant
 rework going on in that subsystem.  Merge required updating to reflect
 some changes in IIO.
 
 Late rebase to fix some wrong fixes tags due to some earlier rebases
 made necessary by messing up the immutable branch.
 
 IIO New Device Support
 * adi,ad5686
   - Add info to support AD5673R and AD5677R
 * bosch,bmi088
   - New driver supporting this accelerometer + gyroscope
 * cros_ec_mkbp
   - New driver for this proximity sensor that exposes a 'front'
     sensor. Very simple switch like device, but driver allows it
     to share interface with more sophisticated proximity sensors.
 * iio_scmi
   - New driver to support ARM SCMI protocol to expose underlying
     accelerometers and gyroscopes via this firmware interface.
 * st,st_magn
   - Add ID for IISMDC magnetometer.
 * ti,ads131e0
   - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
 
 Counter New Device Support
 * IRQ or GPIO based counter
   - New driver for a conceptually simple counter that uses interrupts
     to perform the count.
 
 Features
 * core
   - Dual buffer supprt including:
      Various helpers to centralize handling of bufferer related elements.
      Document existing and new IOCTLs
      Register the IIO chrdev only if it can actually be used for anything.
      Rework attribute group creation in the core (lots of patches)
      Merge buffer/ and scan_elements/ entries into one list + maintain
      backwards compatible set.
      Introduce the internal logic and IOCTL to allow multiple buffers
      + access to an anon FD per buffer to actually read from it.
      Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
      Update ABI docs.
      A few follow up fixes, unsuprising as this was a huge bit of rework.
   - Move common case setting of trig->parent to the core.
   - Provide an iio_read_channel_processed_scale() to avoid loss of
     precision from iio_read_channel_processed() then applying integer
     scale. Use it in ntc_thermistor driver in hwmon.
   - Allow drivers to specify labels from elsewhere than DT. Use it for
     bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
   - Document label usage for proximity and accelerometer sensors.
   - Some local variable renames for consistency
 tools
   - Add -a parameter to iio_event_monitor to allow autoenabling of events.
 * acpi_als
   - Add trigger support for devices that don't support notification method.
 * adi,ad7124
   - Allow more than 8 channels.  This is a complex little device, but is
     capable of supporting up to 16 channels if the share certain
     configuration settings.
 * hrtimer-trigger
   - Support sampling frequency below 1Hz.
 * mediatek,mt8195-auxadc
   - Add compatible to binding docs (always also includes mt8173)
 * st,stm32-adc
   - Enable timetamps when not using DMA.
 * vishay,vcnl3020
   - Sampling frequency control.
 
 Cleanup and minor fixes:
 * treewide
   - Use some getter and setter functions instead of opencoding.
   - Set of fixes for pointless casts in various drivers.
   - Avoid wrong kernel-doc marking on comment blocks.
   - Fix various other minor kernel-doc issues shown by W=1
 * core
   - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
   - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
   - Add unit tests for iio_format_value()
 * docs
   - Fix formatting/typos in iio_configfs.rst and buffers.rst
   - Add documentation of index in buffers.rst
   - Fix scan element description
   - Avoid some issues with HTML generation from ABI docs by moving
     duplicated defintions to more generic files.
   - Drop reference to long dead mailing list.
 * 104-quad
   - Remove left over deprecated IIO counter ABI.
 * adi,adi-axi-adc
   - Fix wrong bit of docs.

   - Fix calculation of sampling frequency when using pulse per second input.
 * adi,adis16475
   - Calculate the IMU scaled internal sampling rate and runtime depending
     on sysfs based configuration rather than getting from DT. Drop now
     unnecessary property from DT bindings doc.
 * cros_ec
    - Fix result of a series of recent changes that means extended buffer
      attributes turn up in the wrong place. Too complex to revert the
      various patches unfortunately so this is a bit messy.
 * fsl,mma3452
   - Indentation cleanup.
 * hid-sensors
   - Size of storage needs to increase for some parts when using quaternions.
   - Move the get sensistivity attribute to hid-sensors-common to reduce
     duplication.  Enable it for more device types.
   - Correctly handle relative sensitivity if reported that way including
     documenting the new ABI.
 * maxim,max517
   - Use device managed functions in probe.
 * mediatek,mt6360-adc

Merge tag 'iio-for-5.13a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

1st set of IIO/counter device support, features and cleanup in the 5.13 cycle

Big set in here from Alexandru Ardelean enabling multiple buffer support.
This includes providing a new directory per buffer that combines
what was previously in buffer/ and scan_elements/. Old interfaces still
in place for compatiblity.

Note immuatable branch for scmi patches to allow for some significant
rework going on in that subsystem.  Merge required updating to reflect
some changes in IIO.

Late rebase to fix some wrong fixes tags due to some earlier rebases
made necessary by messing up the immutable branch.

IIO New Device Support
* adi,ad5686
  - Add info to support AD5673R and AD5677R
* bosch,bmi088
  - New driver supporting this accelerometer + gyroscope
* cros_ec_mkbp
  - New driver for this proximity sensor that exposes a 'front'
    sensor. Very simple switch like device, but driver allows it
    to share interface with more sophisticated proximity sensors.
* iio_scmi
  - New driver to support ARM SCMI protocol to expose underlying
    accelerometers and gyroscopes via this firmware interface.
* st,st_magn
  - Add ID for IISMDC magnetometer.
* ti,ads131e0
  - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs

Counter New Device Support
* IRQ or GPIO based counter
  - New driver for a conceptually simple counter that uses interrupts
    to perform the count.

Features
* core
  - Dual buffer supprt including:
     Various helpers to centralize handling of bufferer related elements.
     Document existing and new IOCTLs
     Register the IIO chrdev only if it can actually be used for anything.
     Rework attribute group creation in the core (lots of patches)
     Merge buffer/ and scan_elements/ entries into one list + maintain
     backwards compatible set.
     Introduce the internal logic and IOCTL to allow multiple buffers
     + access to an anon FD per buffer to actually read from it.
     Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
     Update ABI docs.
     A few follow up fixes, unsuprising as this was a huge bit of rework.
  - Move common case setting of trig->parent to the core.
  - Provide an iio_read_channel_processed_scale() to avoid loss of
    precision from iio_read_channel_processed() then applying integer
    scale. Use it in ntc_thermistor driver in hwmon.
  - Allow drivers to specify labels from elsewhere than DT. Use it for
    bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
  - Document label usage for proximity and accelerometer sensors.
  - Some local variable renames for consistency
tools
  - Add -a parameter to iio_event_monitor to allow autoenabling of events.
* acpi_als
  - Add trigger support for devices that don't support notification method.
* adi,ad7124
  - Allow more than 8 channels.  This is a complex little device, but is
    capable of supporting up to 16 channels if the share certain
    configuration settings.
* hrtimer-trigger
  - Support sampling frequency below 1Hz.
* mediatek,mt8195-auxadc
  - Add compatible to binding docs (always also includes mt8173)
* st,stm32-adc
  - Enable timetamps when not using DMA.
* vishay,vcnl3020
  - Sampling frequency control.

Cleanup and minor fixes:
* treewide
  - Use some getter and setter functions instead of opencoding.
  - Set of fixes for pointless casts in various drivers.
  - Avoid wrong kernel-doc marking on comment blocks.
  - Fix various other minor kernel-doc issues shown by W=1
* core
  - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
  - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
  - Add unit tests for iio_format_value()
* docs
  - Fix formatting/typos in iio_configfs.rst and buffers.rst
  - Add documentation of index in buffers.rst
  - Fix scan element description
  - Avoid some issues with HTML generation from ABI docs by moving
    duplicated defintions to more generic files.
  - Drop reference to long dead mailing list.
* 104-quad
  - Remove left over deprecated IIO counter ABI.
* adi,adi-axi-adc
  - Fix wrong bit of docs.
* adi,ad5791
  - Typos
* adi,ad9834
   - Switch to device managed functions in probe.
* adi,adis*
  - Add and use helpers for locking to reduced duplication.
* adi,adis16480
  - Fix calculation of sampling frequency when using pulse per second input.
* adi,adis16475
  - Calculate the IMU scaled internal sampling rate and runtime depending
    on sysfs based configuration rather than getting from DT. Drop now
    unnecessary property from DT bindings doc.
* cros_ec
   - Fix result of a series of recent changes that means extended buffer
     attributes turn up in the wrong place. Too complex to revert the
     various patches unfortunately so this is a bit messy.
* fsl,mma3452
  - Indentation cleanup.
* hid-sensors
  - Size of storage needs to increase for some parts when using quaternions.
  - Move the get sensistivity attribute to hid-sensors-common to reduce
    duplication.  Enable it for more device types.
  - Correctly handle relative sensitivity if reported that way including
    documenting the new ABI.
* maxim,max517
  - Use device managed functions in probe.
* mediatek,mt6360-adc
  - Use asm/unaligned.h instead of directly including
    unaligned/be_byteshift.h
* novuton,npcm-adc
  - Local lock instead of missusing mlock.
* semtech,sx9500
  - Typos
* st,sensor
  - typo fix
* st,spear-adc
  - Local lock instead of missusing mlock.
* st,stm32-adc
  - Long standing HAS_IOMEM dependency fix.
* st,stm32-counter

46b494f286 thunderbolt: Add support for maxhopid XDomain property
USB4 inter-domain spec mandates that the compatible hosts expose a new
property "maxhopid" that tells the connection manager on the other side
what is the maximum supported input HopID over the connection. Since
this is depend on the lane adapter the cable is connected it needs to be
filled in dynamically.

For this reason we take a copy of the global properties and fill then
for each XDomain connection upon first connect, and then keep updating
it if the generation changes as services are being added/removed. We
also take advantage of this copy to fill in the hostname.

We also expose this maxhopid as an attribute under each XDomain device.

While there drop kernel-doc entry for property_lock which seems to be
left there when the structure was originally introduced.

Since the new change to the IIO buffer infrastructure, the buffer/ and
scan_elements/ directories have been merged into bufferY/ to have some
attributes available per-buffer.

This change updates the ABI docs to reflect this change.

The hwfifo attributes are not updated, as for now these should be used
via the legacy buffer/ directory until they are moved into core.

9a6df4b1ab iio: documentation: Document accelerometer label use
Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges,
have 2 accelerometers, 1 in their base and 1 in their display.

In many cases the kernel can detect the location of each accelerometer
based on e.g. information from the ACPI tables.

It is important for userspace to know the location of the 2 accelerometers.
Rather then adding a new sysfs-attribute for this we can relay this
information to userspace by using standardized label strings for this.
This mirrors how this is done for proximity sensors.

This commit documents 2 new standardized label strings for this purpose:
"accel-base"
"accel-display"

Note the "base" and "display" suffixes were chosen to match the values
used for the systemd/udev hwdb.d/60-sensor.hwdb file's ACCEL_LOCATION
property.

Add an entry to Documentation/ABI/testing/sysfs-bus-iio for
the new device label sysfs-attribute support.

And document the standardized labels which may be used with proximity
sensors to hint userspace about the intended use of the sensor.

Using labels to differentiate between the multiple proximity sensors
which a modern laptop/tablet may have was discussed in this thread:
https://lore.kernel.org/linux-iio/9f9b0ff6-3bf1-63c4-eb36-901cecd7c4d9@redhat.com/

As mentioned there the "proximity-wifi*" labels are already being used
in this manner on some chromebooks, see e.g.:
arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi
arch/arm64/boot/dts/qcom/sc7180-trogdor-lte-sku.dtsi

And the "proximity-palmrest" and "proximity-lap" labels are intended
to be used with the lap and palmrest sensors found in recent Lenovo
ThinkPad models.

a89107c047 Documentation: sysfs/memory: clarify some memory block device properties
In commit 53cdc1cb29 ("drivers/base/memory.c: indicate all memory blocks
as removable") we changed the output of the "removable" property of memory
devices to return "1" if and only if the kernel supports memory offlining.

Let's update documentation, stating that the interface is legacy.  Also
update documentation of the "state" property and "valid_zones" properties.

e9a2e48e87 drivers/base/memory: don't store phys_device in memory blocks
No need to store the value for each and every memory block, as we can
easily query the value at runtime.  Reshuffle the members to optimize the
memory layout.  Also, let's clarify what the interface once was used for
and why it's legacy nowadays.

"phys_device" was used on s390x in older versions of lsmem[2]/chmem[3],
back when they were still part of s390x-tools.  They were later replaced
by the variants in linux-utils.  For example, RHEL6 and RHEL7 contain
lsmem/chmem from s390-utils.  RHEL8 switched to versions from util-linux
on s390x [4].

"phys_device" was added with sysfs support for memory hotplug in commit
3947be1969 ("[PATCH] memory hotplug: sysfs and add/remove functions") in
2005.  It always returned 0.

s390x started returning something != 0 on some setups (if sclp.rzm is set
by HW) in 2010 via commit 57b552ba0b ("memory hotplug/s390: set
phys_device").

For s390x, it allowed for identifying which memory block devices belong to
the same storage increment (RZM).  Only if all memory block devices
comprising a single storage increment were offline, the memory could
actually be removed in the hypervisor.

Since commit e5d709bb5f ("s390/memory hotplug: provide
memory_block_size_bytes() function") in 2013 a memory block device spans
at least one storage increment - which is why the interface isn't really
helpful/used anymore (except by old lsmem/chmem tools).

There were once RFC patches to make use of "phys_device" in ACPI context;
however, the underlying problem could be solved using different interfaces
[1].

e229b429bb Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
 5.12-rc1.  Over time it seems like this tree is collecting more and more
 tiny driver subsystems in one place, making it easier for those
 maintainers, which is why this is getting larger.
 
 Included in here are:
 	- coresight driver updates
 	- habannalabs driver updates
 	- virtual acrn driver addition (proper acks from the x86
 	  maintainers)
 	- broadcom misc driver addition
 	- speakup driver updates
 	- soundwire driver updates
 	- fpga driver updates
 	- amba driver updates
 	- mei driver updates

 	- phy driver updates
 	- mhi driver updates
 	- interconnect driver udpates
 	- fsl-mc bus driver updates
 	- random driver fix
 	- some small misc driver updates (rtsx, pvpanic, etc.)
 
 All of these have been in linux-next for a while, with the only reported
 issue being a merge conflict in include/linux/mod_devicetable.h that you
 will hit in your tree due to the dfl_device_id addition from the fpga
 subsystem in here.  The resolution should be simple.

825d150875 cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is
 Compute Express Link which released the 2.0 specification in November.
 The Linux relevant changes in CXL 2.0 are support for an OS to
 dynamically assign address space to memory devices, support for
 switches, persistent memory, and hotplug. A Type-3 Memory Device is a
 PCI enumerated device presenting the CXL Memory Device Class Code and
 implementing the CXL.mem protocol. CXL.mem allows device to advertise
 CPU and I/O coherent memory to the system, i.e. typical "System RAM" and
 "Persistent Memory" in Linux /proc/iomem terms.
 
 In addition to the CXL.mem fast path there is an administrative command
 hardware mailbox interface for maintenance and provisioning. It is this
 command interface that is the focus of the initial driver. With this
 driver a CXL device that is mapped by the BIOS can be administered by
 Linux. Linux support for CXL PMEM and dynamic CXL address space
 management are to be implemented post v5.12.

06f45fe96f xen/events: add per-xenbus device event statistics and settings
Add syfs nodes for each xenbus device showing event statistics (number
of events and spurious events, number of associated event channels)
and for setting a spurious event threshold in case a frontend is
sending too many events without being rogue on purpose.

820c872795 Input: cros-ec-keyb - expose function row physical map to userspace
The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".

Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the function key code and do the conversion
whenever necessary.

Since the userpace already knows the key scanlines (row/column)
associated with a received key code. Essentially, the userspace only
needs a mapping between the key row/column and the matching physical
location in the top row.

So, enhance the cros-ec-keyb driver to create such a mapping
and expose it to userspace in the form of a function_row_physmap
attribute. The attribute would be a space separated ordered list of
row/column codes for the keys in the function row, in a left-to-right
order.

The attribute will only be present when the device has a custom design
for the top-row keys.

This series consists of the usual driver updates (ufs, ibmvfc,
 qla2xxx, hisi_sas, pm80xx) plus the removal of the gdth driver (which
 is bound to cause conflicts with a trivial change somewhere).  The
 only big major rework of note is the one from Hannes trying to clean

8b42fe123b f2fs-for-5.12-rc1
We've added two major features: 1) compression level and 2) checkpoint_merge, in
 this round. 1) compression level expands 'compress_algorithm' mount option to
 accept parameter as format of <algorithm>:<level>, by this way, it gives a way
 to allow user to do more specified config on lz4 and zstd compression level,
 then f2fs compression can provide higher compress ratio. 2) checkpoint_merge
 creates a kernel daemon and makes it to merge concurrent checkpoint requests as
 much as possible to eliminate redundant checkpoint issues. Plus, we can
 eliminate the sluggish issue caused by slow checkpoint operation when the
 checkpoint is done in a process context in a cgroup having low i/o budget and
 cpu shares.
 
 Enhancement:
  - add compress level for lz4 and zstd in mount option
  - checkpoint_merge mount option
  - deprecate f2fs_trace_io
 
 Bug fix:
  - flush data when enabling checkpoint back
  - handle corner cases of mount options
  - missing ACL update and lock for I_LINKABLE flag
  - attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
  - fix potential deadlock in compression flow
  - fix wrong submit_io condition
 
 As usual, we've cleaned up many code flows and fixed minor bugs.

5d99aa093b Staging/IIO driver patches for 5.12-rc1
Here is the "big" set of staging and IIO driver patches for 5.12-rc1.
 
 Nothing really huge in here, the number of staging tree patches has gone
 down for a bit, maybe there's only so much churn to happen in here at
 the moment.
 
 The IIO changes are:
 	- new drivers
 	- new DT bindings
 	- new iio driver features
 with full details in the shortlog.
 
 The staging driver patches are just a lot of tiny coding style cleanups,
 along with some semi-larger hikey driver cleanups as those are _almost_
 good enough to get out of the staging tree, but will probably have to
 wait until 5.13 to have happen.
 
 All of these have been in linux-next with no reported issues.

   - new drivers

   - new DT bindings

   - new iio driver features

  The staging driver patches are just a lot of tiny coding style
  cleanups, along with some semi-larger hikey driver cleanups as those
  are _almost_ good enough to get out of the staging tree, but will
  probably have to wait until 5.13 to have happen.

b39cb1052a cxl/mem: Register CXL memX devices
Create the /sys/bus/cxl hierarchy to enumerate:

* Memory Devices (per-endpoint control devices)

* Memory Address Space Devices (platform address ranges with
  interleaving, performance, and persistence attributes)

* Memory Regions (active provisioned memory from an address space device
  that is in use as System RAM or delegated to libnvdimm as Persistent
  Memory regions).

For now, only the per-endpoint control devices are registered on the
'cxl' bus. However, going forward it will provide a mechanism to
coordinate cross-device interleave.

c068e3f484 Drivers: hv: vmbus: Add /sys/bus/vmbus/hibernation
When a Linux VM runs on Hyper-V, if the host toolstack doesn't support
hibernation for the VM (this happens on old Hyper-V hosts like Windows
Server 2016, or new Hyper-V hosts if the admin or user doesn't declare
the hibernation intent for the VM), the VM is discouraged from trying
hibernation (because the host doesn't guarantee that the VM's virtual
hardware configuration will remain exactly the same across hibernation),
i.e. the VM should not try to set up the swap partition/file for
hibernation, etc.

x86 Hyper-V uses the presence of the virtual ACPI S4 state as the
indication of the host toolstack support for a VM. Currently there is
no easy and reliable way for the userspace to detect the presence of
the state (see https://lkml.org/lkml/2020/12/11/1097).  Add
/sys/bus/vmbus/hibernation for this purpose.

5fdd2f0e5c net: add sysfs attribute to control napi threaded mode
This patch adds a new sysfs attribute to the network device class.
Said attribute provides a per-device control to enable/disable the
threaded mode for all the napi instances of the given network device,
without the need for a device up/down.
User sets it to 1 or 0 to enable or disable threaded mode.
Note: when switching between threaded and the current softirq based mode
for a napi instance, it will not immediately take effect if the napi is
currently being polled. The mode switch will happen for the next time
napi_schedule() is called.

6b49dea4fd platform/x86: ideapad-laptop: add "always on USB charging" control support
Certain models have a so-called "always on USB charging" feature,
which enables USB charging even when the computer is turned off
or suspended, and which may be controlled/queried using the
SALS/HALS ACPI methods. Expose this functionality via a new device
attribute (usb_charging). Tested on: Lenovo YOGA 520-14IKB 80X8

3cd542e6e6 thunderbolt: Add support for PCIe tunneling disabled (SL5)
Recent Intel Thunderbolt firmware connection manager has support for
another security level, SL5, that disables PCIe tunneling. This option
can be turned on from the BIOS.

When this is set the driver exposes a new security level "nopcie" to the
userspace and hides the authorized attribute under connected devices.

While there we also hide it when "dponly" security level is enabled
since it is not really usable in that case anyway.

f5030e2526 usb: typec: Provide PD Specification Revision for cable and partner
The USB Power Delivery specification Section 6.2.1.1.5 outlines
revision backward compatibility requirements starting from Revision 3.0.

The Port, the Cable Plug, and the Port Partner may support either
revision 2 or revision 3 independently, and communication between ports,
partners, and cables of different revisions are allowed under rules
that the parties agree to communicate between each other using the
lowest common operating revision.

This may mean that Port-to-Partner operating revision comms may be
different than Port-to-CablePlug operating revision comms. For example,
it is possible for a R3.0 port to communicate with a R3.0 partner
using R3.0 messages, while the R3.0 port (in the same session) must
communicate with the R2.0 cable using R2.0 messages only.

Introduce individual revision number properties for cable
and port partner so that the port can track them independently.

53da0ebaad net: dsa: allow changing the tag protocol via the "tagging" device attribute
Currently DSA exposes the following sysfs:
$ cat /sys/class/net/eno2/dsa/tagging
ocelot

which is a read-only device attribute, introduced in the kernel as
commit 98cdb48071 ("net: dsa: Expose tagging protocol to user-space"),
and used by libpcap since its commit 993db3800d7d ("Add support for DSA
link-layer types").

It would be nice if we could extend this device attribute by making it
writable:
$ echo ocelot-8021q > /sys/class/net/eno2/dsa/tagging

This is useful with DSA switches that can make use of more than one
tagging protocol. It may be useful in dsa_loop in the future too, to
perform offline testing of various taggers, or for changing between dsa
and edsa on Marvell switches, if that is desirable.

In terms of implementation, drivers can support this feature by
implementing .change_tag_protocol, which should always leave the switch
in a consistent state: either with the new protocol if things went well,
or with the old one if something failed. Teardown of the old protocol,
if necessary, must be handled by the driver.

Some things remain as before:
- The .get_tag_protocol is currently only called at probe time, to load
  the initial tagging protocol driver. Nonetheless, new drivers should
  report the tagging protocol in current use now.
- The driver should manage by itself the initial setup of tagging
  protocol, no later than the .setup() method, as well as destroying
  resources used by the last tagger in use, no earlier than the
  .teardown() method.

For multi-switch DSA trees, error handling is a bit more complicated,
since e.g. the 5th out of 7 switches may fail to change the tag
protocol. When that happens, a revert to the original tag protocol is
attempted, but that may fail too, leaving the tree in an inconsistent
state despite each individual switch implementing .change_tag_protocol
transactionally. Since the intersection between drivers that implement
.change_tag_protocol and drivers that support D in DSA is currently the
empty set, the possibility for this error to happen is ignored for now.

b3f82afc10 IMA: Measure kernel version in early boot
The integrity of a kernel can be verified by the boot loader on cold
boot, and during kexec, by the current running kernel, before it is
loaded. However, it is still possible that the new kernel being
loaded is older than the current kernel, and/or has known
vulnerabilities. Therefore, it is imperative that an attestation
service be able to verify the version of the kernel being loaded on
the client, from cold boot and subsequent kexec system calls,
ensuring that only kernels with versions known to be good are loaded.

Measure the kernel version using ima_measure_critical_data() early on
in the boot sequence, reducing the chances of known kernel
vulnerabilities being exploited. With IMA being part of the kernel,
this overall approach makes the measurement itself more trustworthy.

To enable measuring the kernel version "ima_policy=critical_data"
needs to be added to the kernel command line arguments.
For example,
        BOOT_IMAGE=/boot/vmlinuz-5.11.0-rc3+ root=UUID=fd643309-a5d2-4ed3-b10d-3c579a5fab2f ro nomodeset ima_policy=critical_data

If runtime measurement of the kernel version is ever needed, the
following should be added to /etc/ima/ima-policy:

        measure func=CRITICAL_DATA label=kernel_info

To extract the measured data after boot, the following command can be used:

        grep -m 1 "kernel_version" \
        /sys/kernel/security/integrity/ima/ascii_runtime_measurements

Sample output from the command above:

        10 a8297d408e9d5155728b619761d0dd4cedf5ef5f ima-buf
        sha256:5660e19945be0119bc19cbbf8d9c33a09935ab5d30dad48aa11f879c67d70988

The above hex-ascii string corresponds to the kernel version
(e.g. xxd -r -p):

e020ff611b driver core: Fix device link device name collision
The device link device's name was of the form:
<supplier-dev-name>--<consumer-dev-name>

This can cause name collision as reported here [1] as device names are
not globally unique. Since device names have to be unique within the
bus/class, add the bus/class name as a prefix to the device names used to
construct the device link device name.

So the devuce link device's name will be of the form:
<supplier-bus-name>:<supplier-dev-name>--<consumer-bus-name>:<consumer-dev-name>

3da88be249 thunderbolt: Add support for de-authorizing devices
In some cases it is useful to be able de-authorize devices. For example
if user logs out the userspace can have a policy that disconnects PCIe
devices until logged in again. This is only possible for software based
connection manager as it directly controls the tunnels.

For this reason make the authorized attribute accept writing 0 which
makes the software connection manager to tear down the corresponding
PCIe tunnel. Userspace can check if this is supported by reading a new
domain attribute deauthorization, that holds 1 in that case.

While there correct tb_domain_approve_switch() kernel-doc and
description of authorized attribute to mention that it is only about
PCIe tunnels.

fdd1ffe8a8 selinux: include a consumer of the new IMA critical data hook
SELinux stores the active policy in memory, so the changes to this data
at runtime would have an impact on the security guarantees provided
by SELinux.  Measuring in-memory SELinux policy through IMA subsystem
provides a secure way for the attestation service to remotely validate
the policy contents at runtime.

Measure the hash of the loaded policy by calling the IMA hook
ima_measure_critical_data().  Since the size of the loaded policy
can be large (several MB), measure the hash of the policy instead of
the entire policy to avoid bloating the IMA log entry.

To enable SELinux data measurement, the following steps are required:

1, Add "ima_policy=critical_data" to the kernel command line arguments
   to enable measuring SELinux data at boot time.
For example,
  BOOT_IMAGE=/boot/vmlinuz-5.10.0-rc1+ root=UUID=fd643309-a5d2-4ed3-b10d-3c579a5fab2f ro nomodeset security=selinux ima_policy=critical_data

2, Add the following rule to /etc/ima/ima-policy
   measure func=CRITICAL_DATA label=selinux

Sample measurement of the hash of SELinux policy:

To verify the measured data with the current SELinux policy run
the following commands and verify the output hash values match.

  sha256sum /sys/fs/selinux/policy | cut -d' ' -f 1

  grep "selinux-policy-hash" /sys/kernel/security/integrity/ima/ascii_runtime_measurements | tail -1 | cut -d' ' -f 6

Note that the actual verification of SELinux policy would require loading
the expected policy into an identical kernel on a pristine/known-safe
system and run the sha256sum /sys/kernel/selinux/policy there to get
the expected hash.

47d76a4840 IMA: limit critical data measurement based on a label
Integrity critical data may belong to a single subsystem or it may
arise from cross subsystem interaction.  Currently there is no mechanism
to group or limit the data based on certain label.  Limiting and
grouping critical data based on a label would make it flexible and
configurable to measure.

Define "label:=", a new IMA policy condition, for the IMA func
CRITICAL_DATA to allow grouping and limiting measurement of integrity
critical data.

Limit the measurement to the labels that are specified in the IMA
policy - CRITICAL_DATA+"label:=".  If "label:=" is not provided with
the func CRITICAL_DATA, measure all the input integrity critical data.

c4e43aa2ee IMA: add policy rule to measure critical data
A new IMA policy rule is needed for the IMA hook
ima_measure_critical_data() and the corresponding func CRITICAL_DATA for
measuring the input buffer.  The policy rule should ensure the buffer
would get measured only when the policy rule allows the action.  The
policy rule should also support the necessary constraints (flags etc.)
for integrity critical buffer data measurements.

Add policy rule support for measuring integrity critical data.

This driver is for the EMIF private feature implemented under FPGA
Device Feature List (DFL) framework. It is used to expose memory
interface status information as well as memory clearing control.

The purpose of memory clearing block is to zero out all private memory
when FPGA is to be reprogrammed. This gives users a reliable method to
prevent potential data leakage.

56172ab353 fpga: dfl: add support for N3000 Nios private feature
This patch adds support for the Nios handshake private feature on Intel
PAC (Programmable Acceleration Card) N3000.

The Nios is the embedded processor on the FPGA card. This private feature
provides a handshake interface to FPGA Nios firmware, which receives
retimer configuration command from host and executes via an internal SPI
master (spi-altera). When Nios finishes the configuration, host takes over
the ownership of the SPI master to control an Intel MAX10 BMC (Board
Management Controller) Chip on the SPI bus.

For Nios firmware handshake part, this driver requests the retimer
configuration for Nios firmware on probe, and adds some sysfs nodes for
user to query the onboard retimer's working mode and Nios firmware
version.

For SPI part, this driver adds a spi-altera platform device as well as
the MAX10 BMC spi slave info. A spi-altera driver will be matched to
handle the following SPI work.

8e0cbf3563 Documentation: Add documentation for new platform_profile sysfs attribute
On modern systems the platform performance, temperature, fan and other
hardware related characteristics are often dynamically configurable. The
profile is often automatically adjusted to the load by some
automatic-mechanism (which may very well live outside the kernel).

These auto platform-adjustment mechanisms often can be configured with
one of several 'platform-profiles', with either a bias towards low-power
consumption or towards performance (and higher power consumption and
thermals).

Introduce a new platform_profile sysfs API which offers a generic API for
selecting the performance-profile of these automatic-mechanisms.

ff49c86f27 f2fs-for-5.11-rc1
In this round, we've made more work into per-file compression support. For
 example, F2FS_IOC_GET|SET_COMPRESS_OPTION provides a way to change the
 algorithm or cluster size per file. F2FS_IOC_COMPRESS|DECOMPRESS_FILE provides
 a way to compress and decompress the existing normal files manually along with
 a new mount option, compress_mode=fs|user, which can control who compresses the
 data. Chao also added a checksum feature with a mount option so that we are able
 to detect any corrupted cluster. In addition, Daniel contributed casefolding
 with encryption patch, which will be used for Android devices.
 
 Enhancement:
  - add ioctls and mount option to manage per-file compression feature
  - support casefolding with encryption
  - support checksum for compressed cluster
  - avoid IO starvation by replacing mutex with rwsem
  - add sysfs, max_io_bytes, to control max bio size
 
 Bug fix:
  - fix use-after-free issue when compression and fsverity are enabled
  - fix consistency corruption during fault injection test
  - fix data offset for lseek
  - get rid of buffer_head which has 32bits limit in fiemap
  - fix some bugs in multi-partitions support
  - fix nat entry count calculation in shrinker
  - fix some stat information
 
 And, we've refactored some logics and fix minor bugs as well.

Merge tag 'f2fs-for-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've made more work into per-file compression support.

  For example, F2FS_IOC_GET | SET_COMPRESS_OPTION provides a way to
  change the algorithm or cluster size per file. F2FS_IOC_COMPRESS |
  DECOMPRESS_FILE provides a way to compress and decompress the existing
  normal files manually.

  There is also a new mount option, compress_mode=fs|user, which can
  control who compresses the data.

  Chao also added a checksum feature with a mount option so that
  we are able to detect any corrupted cluster.

  In addition, Daniel contributed casefolding with encryption patch,
  which will be used for Android devices.

  Summary:

  Enhancements:
   - add ioctls and mount option to manage per-file compression feature
   - support casefolding with encryption
   - support checksum for compressed cluster
   - avoid IO starvation by replacing mutex with rwsem
   - add sysfs, max_io_bytes, to control max bio size

  Bug fixes:
   - fix use-after-free issue when compression and fsverity are enabled
   - fix consistency corruption during fault injection test
   - fix data offset for lseek
   - get rid of buffer_head which has 32bits limit in fiemap
   - fix some bugs in multi-partitions support
   - fix nat entry count calculation in shrinker
   - fix some stat information

  And, we've refactored some logics and fix minor bugs as well"

Pull IOMMU updates from Will Deacon:
 "There's a good mixture of improvements to the core code and driver
  changes across the board.

  One thing worth pointing out is that this includes a quirk to work
  around behaviour in the i915 driver (see 65f746e828 ("iommu: Add
  quirk for Intel graphic devices in map_sg")), which otherwise
  interacts badly with the conversion of the intel IOMMU driver over to
  the DMA-IOMMU APU but has being fixed properly in the DRM tree.

  We'll revert the quirk later this cycle once we've confirmed that
  things don't fall apart without it.

2c622ed0ea reboot: allow to specify reboot mode via sysfs
The kernel cmdline reboot= option offers some sort of control on how the
reboot is issued.

We don't always know in advance what type of reboot to perform.

Sometimes a warm reboot is preferred to persist certain memory regions
across the reboot.  Others a cold one is needed to apply a future system
update that makes a memory memory model change, like changing the base
page size or resizing a persistent memory region.

Or simply we want to enable reboot_force because we noticed that
something bad happened.

Add handles in sysfs to allow setting these reboot options, so they can
be changed when the system is booted, other than at boot time.

The handlers are under <sysfs>/kernel/reboot, can be read to get the
current configuration and written to alter it.

	# cd /sys/kernel/reboot/

	# grep . *
	cpu:0
	force:0
	mode:cold
	type:acpi

	# echo 2 >cpu
	# echo yes >force
	# echo soft >mode
	# echo bios >type

	# grep . *
	cpu:2
	force:1
	mode:soft
	type:bios

Before setting anything, check for CAP_SYS_BOOT capability, so it's
possible to allow an unpriviledged process to change these settings simply
by relaxing the handles permissions, without opening them to the world.

3db1a3fa98 Staging / IIO driver patches for 5.11-rc1
Here is the big staging and IIO driver pull request for 5.11-rc1
 
 Lots of different things in here:
   - loads of driver updates
   - so many coding style cleanups
   - new IIO drivers
   - Android ION code is finally removed from the tree
   - wimax drivers are moved to staging on their way out of the kernel
 
 Nothing really exciting, just the constant grind of kernel development :)
 
 All have been in linux-next for a while with no reported issues.

d635a69dd4 Networking updates for 5.11
Core:
 
  - support "prefer busy polling" NAPI operation mode, where we defer softirq
    for some time expecting applications to periodically busy poll
 
  - AF_XDP: improve efficiency by more batching and hindering
            the adjacency cache prefetcher
 
  - af_packet: make packet_fanout.arr size configurable up to 64K
 
  - tcp: optimize TCP zero copy receive in presence of partial or unaligned

           many smaller improvements
 
  - TLS: support CHACHA20-POLY1305 cipher
 
  - seg6: add support for SRv6 End.DT4/DT6 behavior
 
  - sctp: Implement RFC 6951: UDP Encapsulation of SCTP

Rafael J. Wysocki
d3569c149d Update devfreq for 5.11
Detailed description for this pull request:
 
 1. Update devfreq core
 - Add new devfreq_frequency tracepoint to show the frequency change
 information.
 
 - Add governor feature flag. The devfreq governor is able to
 have the specific flag in order to contain the non-common feature.
 For example, if governor contains the 'immutable' feature, don't allow
 user to change the governor via sysfs.
 
 - Add governor sysfs attribute flag for each sysfs file. Prior to that
 devfreq subsystem show the all sysfs files regardless of governor type.
 But, some sysfs fils are not supported on the specific devfreq governor.
 In order to show the only supported sysfs files according to the governor,
 clarify the access permission of sysfs attributes according to governor.
 When adding the devfreq governor, can specify the available attribute
 information by using DEVFREQ_GOV_ATTR_* constant variable. The user can
 read or write the sysfs attributes in accordance to the specified attributes.
 
 - Clean-up the code to remove the duplicate code for the devfreq tracepoint
 and to remove redundant governor_name field from struct devfreq
 
 2. Update exynos-bus.c devfreq driver
 - Add interconnect API support for the Samsung Exynos Bus Frequency driver

 functionality allows to ensure the QoS requirements of devices accessing
 the system memory (e.g. video processing devices) are fulfilled
 and allows to avoid issues like the DMA underrun.
 
 3. Update tegra devfreq driver

 Also, it is to guarantee the QoS requirement of some devices like
 display controller.
 
 - Move tegra20-devfreq.c from drivers/devfreq/ into driver/memory/tegra/
 in order to use the more proper monitoring feature such as EMC_STAT
 which is based in driver/memory/tegra/.
 
 - Separate the configuration information for different SoC on
 tegra30-devfrqe.c. The tegra30-devfreq.c had been supported both
 tegra30-actmon and tegra124-actmon devices. In order to use
 the more correct configuration data, separate them.

Merge tag 'devfreq-next-for-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq updates for 5.11 from Chanwoo Choi:

 1. Update devfreq core

  - Add new devfreq_frequency tracepoint to show the frequency change
    information.

  - Add governor feature flag. The devfreq governor is able to set the
    specific flag in order to support a non-common feature. For
    example, if the governor supports the 'immutable' feature, don't
    allow user space to change the governor via sysfs.

  - Add governor sysfs attribute flag for each sysfs file. Prior to that
    the devfreq subsystem allowed all of the sysfs files to be accessed
    regardless of the governor type. But some sysfs fils are not
    supported by specific devfreq governors. In order to only allow the
    sysfs files supported by the governor to be accessed, clarify the
    access permissions of sysfs attributes according to the governor.
    When adding the devfreq governor, specify the available attribute
    information by using DEVFREQ_GOV_ATTR_* symbols. The user can read
    or write the sysfs attributes in accordance to the specified
    access permissions.

  - Clean-up the code to reduce duplication for the devfreq tracepoint
    and to remove redundant governor_name field from struct devfreq.

 2. Update exynos-bus.c devfreq driver

  - Add interconnect API support to the Samsung Exynos Bus Frequency
    driver, exynos-bus.c. Complementing the devfreq driver with
    interconnect functionality allows to ensure that the QoS
    requirements regarding devices accessing the system memory (e.g.
    video processing devices) will be met and allows to avoid issues
    like DMA underrun.

 3. Update tegra devfreq driver

  - Add interconnect support and OPP interface to tegra30-devfreq.c.
    Also, it is to guarantee the QoS requirement of some devices like
    the display controller.

  - Move tegra20-devfreq.c from drivers/devfreq/ into drivers/memory/tegra/
    in order to use the more proper monitoring feature such as EMC_STAT
    which is located in drivers/memory/tegra/.

  - Separate the configuration information for different SoCs in

80a129afb7 PCI: Add sysfs attribute for device power state
While PCI power states D0-D3hot can be queried from user-space via lspci,
D3cold cannot.  lspci cannot provide an accurate value when the device is
in D3cold as it has to restore the device to D0 before it can access its
power state via the configuration space, leading to it reporting D0 or
another on-state. Thus lspci cannot be used to diagnose power consumption
issues for devices that can enter D3cold or to ensure that devices properly
enter D3cold at all.

Add a new sysfs device attribute for the PCI power state, showing the
current power state as seen by the kernel.

ab37fa851c usb: typec: Add type sysfs attribute file for partners
USB Power Delivery Specification defines a set of product
types for partners and cables. The product type can be read
from the ID Header VDO which is the first object in the
response to the Discover Identity command. This attribute
will display the product type of the partner. The cables
already have the attribute.

This sysfs attribute file is only created for the partners
and cables if the product type is really known in the
driver. Some interfaces do not give access to the Discover
Identity response from the partner or cable, but they may
still supply the product type separately in some cases.

When the product type of the partner or cable is detected,
uevent is also raised with PRODUCT_TYPE set to show the
actual product type (for example PRODUCT_TYPE=host).

e1e52361c6 usb: typec: Add plug num_altmodes sysfs attr
Add a field to the typec_plug struct to record the number of available
altmodes as well as the corresponding sysfs attribute to expose this to
userspace.

This allows userspace to determine whether there are any
remaining alternate modes left to be registered by the kernel driver. It
can begin executing any policy state machine after all available
alternate modes have been registered with the connector class framework.

This value is set to "-1" initially, signifying that a valid number of
alternate modes haven't been set for the plug. The sysfs file remains
hidden as long as the attribute value is -1.

We re-use the partner attribute for number_of_alternate_modes since the
usage and name is similar, and update the corresponding *_show() command
to support both partner and plugs.

Daniel Borkmann says:

====================
pull-request: bpf-next 2020-11-14

1) Add BTF generation for kernel modules and extend BTF infra in kernel
   e.g. support for split BTF loading and validation, from Andrii Nakryiko.

2) Support for pointers beyond pkt_end to recognize LLVM generated patterns
   on inlined branch conditions, from Alexei Starovoitov.

3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh.

4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage
   infra, from Martin KaFai Lau.

5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the
   XDP_REDIRECT path, from Lorenzo Bianconi.

6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI
   context, from Song Liu.

7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build
   for different target archs on same source tree, from Jean-Philippe Brucker.

8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet.

9) Move functionality from test_tcpbpf_user into the test_progs framework so it
   can run in BPF CI, from Alexander Duyck.

10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner.

Note that for the fix from Song we have seen a sparse report on context
imbalance which requires changes in sparse itself for proper annotation
detection where this is currently being discussed on linux-sparse among
developers [0]. Once we have more clarification/guidance after their fix,
Song will follow-up.

36e68442d1 bpf: Load and verify kernel module BTFs
Add kernel module listener that will load/validate and unload module BTF.
Module BTFs gets ID generated for them, which makes it possible to iterate
them with existing BTF iteration API. They are given their respective module's
names, which will get reported through GET_OBJ_INFO API. They are also marked
as in-kernel BTFs for tooling to distinguish them from user-provided BTFs.

Also, similarly to vmlinux BTF, kernel module BTFs are exposed through
sysfs as /sys/kernel/btf/<module-name>. This is convenient for user-space
tools to inspect module BTF contents and dump their types with existing tools:

5ef9998c96 platform/x86: Intel PMT Crashlog capability driver
Add support for the Intel Platform Monitoring Technology crashlog
interface. This interface provides a few sysfs values to allow for
controlling the crashlog telemetry interface as well as a character
driver to allow for mapping the crashlog memory region so that it can be
accessed after a crashlog has been recorded.

This driver is meant to only support the server version of the crashlog
which is identified as crash_type 1 with a version of zero. Currently no
other types are supported.

e2729113ce platform/x86: Intel PMT class driver
Intel Platform Monitoring Technology is meant to provide a common way to
access telemetry and system metrics.

Register mappings are not provided by the driver. Instead, a GUID is read
from a header for each endpoint. The GUID identifies the device and is to
be used with an XML, provided by the vendor, to discover the available set
of metrics and their register mapping.  This allows firmware updates to
modify the register space without needing to update the driver every time
with new mappings. Firmware writes a new GUID in this case to specify the
new mapping.  Software tools with access to the associated XML file can
then interpret the changes.

The module manages access to all Intel PMT endpoints on a system,
independent of the device exporting them. It creates an intel_pmt class
to manage the devices. For each telemetry endpoint, sysfs files provide
GUID and size information as well as a pointer to the parent device the
telemetry came from. Software may discover the association between
endpoints and devices by iterating through the list in sysfs, or by looking
for the existence of the class folder under the device of interest.  A
binary sysfs attribute of the same name allows software to then read or map
the telemetry space for direct access.

bd6e8441c2 docs: ABI: sysfs-class-backlight: unify ABI documentation
Both adp8860 and adp8870 define some extensions to the
backlight class. This causes warnings:

	Warning: /sys/class/backlight/<backlight>/ambient_light_level is defined 2 times:  /sys/class/backlight/<backlight>/ambient_light_level:8  /sys/class/backlight/<backlight>/ambient_light_level:30

As ABI definitions shouldn't be duplicated.

Unfortunately, the ABI is dependent on the specific device
features. As such, ambient_light_level range is somewhat
different among the supported devices.

The ambient_light_zone is even worse: the meanings of each
preset are different, and there's no ABI to retrieve
the supported types nor their meanins. Unfortunately,
it is too late to fix it without causing regressions,
as this has been used since Kernel v2.6.35.

Rewrite those ABI documentation using the current documentation
as a reference, and double-checking at the datasheets:

	https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8870.pdf
	https://www.analog.com/media/en/technical-documentation/data-sheets/ADP8860.pdf

The Dell WMI Systems Management Driver provides a sysfs
interface for systems management to enable BIOS configuration
capability on certain Dell Systems.

This driver allows user to configure Dell systems with a
uniform common interface. To facilitate this, the patch
introduces a generic way for driver to be able to create
configurable BIOS Attributes available in Setup (F2) screen.

5f1a9066fc PM / devfreq: Add governor attribute flag for specifc sysfs nodes
DEVFREQ supports the default governors like performance, simple_ondemand and
also allows the devfreq driver to add their own governor like tegra30-devfreq.c
according to their requirement. In result, some sysfs attributes are useful
or not useful. Prior to that the user can access all sysfs attributes
regardless of the available attributes.

So, clarify the access permission of sysfs attributes according to governor.
When adding the devfreq governor, can specify the available attribute
information by using DEVFREQ_GOV_ATTR_* constant variable. The user can
read or write the sysfs attributes in accordance to the specified attributes.

When adding the governor, can add the following attributes
according to the governor feature.

[Definition for speific sysfs attributes]
- DEVFREQ_GOV_ATTR_POLLING_INTERVAL to update polling interval for timer.
  : /sys/class/devfreq/[devfreq dev name]/polling_interval
- DEVFREQ_GOV_ATTR_TIMER to change the type of timer on either deferrable
  or dealyed timer.
  : /sys/class/devfreq/[devfreq dev name]/timer

And all devfreq governors have to support the following common attributes.
The common attributes are added to devfreq class by default.
- governor
- available_governors
- available_frequencies
- cur_freq
- target_freq
- min_freq
- max_freq
- trans_stat

Persistent grants feature provides high scalability.  On some small

required to be disabled.  It can be disabled from blkback side using a
module parameter, 'feature_persistent'.  But, it is impossible from
blkfront side.  For the reason, this commit adds a blkfront module
parameter for disabling of the feature.

The typical set of driver updates across the subsystem:
 
  - Driver minor changes and bug fixes for mlx5, efa, rxe, vmw_pvrdma, hns,
    usnic, qib, qedr, cxgb4, hns, bnxt_re
 
  - Various rtrs fixes and updates
 
  - Bug fix for mlx4 CM emulation for virtualization scenarios where MRA
    wasn't working right
 
  - Use tracepoints instead of pr_debug in the CM code
 
  - Scrub the locking in ucma and cma to close more syzkaller bugs
 
  - Use tasklet_setup in the subsystem
 
  - Revert the idea that 'destroy' operations are not allowed to fail at
    the driver level. This proved unworkable from a HW perspective.
 
  - Revise how the umem API works so drivers make fewer mistakes using it
 
  - XRC support for qedr
 
  - Convert uverbs objects RWQ and MW to new the allocation scheme
 
  - Large queue entry sizes for hns

7a3dadedc8 f2fs-for-5.10-rc1
In this round, we've added new features such as zone capacity for ZNS and
 a new GC policy, ATGC, along with in-memory segment management. In addition,
 we could improve the decompression speed significantly by changing virtual
 mapping method. Even though we've fixed lots of small bugs in compression
 support, I feel that it becomes more stable so that I could give it a try in
 production.
 
 Enhancement:
  - suport zone capacity in NVMe Zoned Namespace devices
  - introduce in-memory current segment management
  - add standart casefolding support
  - support age threshold based garbage collection
  - improve decompression speed by changing virtual mapping method
 
 Bug fix:
  - fix condition checks in some ioctl() such as compression, move_range, etc
  - fix 32/64bits support in data structures
  - fix memory allocation in zstd decompress
  - add some boundary checks to avoid kernel panic on corrupted image
  - fix disallowing compression for non-empty file
  - fix slab leakage of compressed block writes
 
 In addition, it includes code refactoring for better readability and minor
 bug fixes for compression and zoned device support.

    powerpc, as well as a related fix for sparc.
 
  - Remove support for PowerPC 601.
 
  - Some fixes for watchpoints & addition of a new ptrace flag for detecting ISA
    v3.1 (Power10) watchpoint features.
 
  - A fix for kernels using 4K pages and the hash MMU on bare metal Power9
    systems with > 16TB of RAM, or RAM on the 2nd node.
 
  - A basic idle driver for shallow stop states on Power10.
 
  - Tweaks to our sched domains code to better inform the scheduler about the
    hardware topology on Power9/10, where two SMT4 cores can be presented by
    firmware as an SMT8 core.
 
  - A series doing further reworks & cleanups of our EEH code.
 
  - Addition of a filter for RTAS (firmware) calls done via sys_rtas(), to
    prevent root from overwriting kernel memory.

c48b75b727 sound updates for 5.10
The amount of changes is smaller at this round (what a surprise),
 but lots of activity is seen.  Most of changes are about ASoC
 driver development, especially Intel platforms.
 Here are some highlights:
 
 General:
 * Replace all tasklet usages with other alternatives
 * Cleanup of the ASoC error unwinding code
 * Fixes for trivial issues caught by static checker
 * Spell fixes allover the places
 
 ALSA Core:
 * Lockdep fix for control devices
 * Fix for potential OSS sequencer mutex stalls
 
 HD-audio and USB-audio:
 * SoundBlaster AE-7 support
 * Changes in quirk table for the rename handling
 * Quirks for HP and ASUS machines, Pioneer DJ DJM-250MK2.
 
 ASoC:
 * Lots of updates for Intel SOF and SoundWire enablement
 * Replacement of the DSP driver for some older x86 systems;
   the new code was written from scratch, better maintenance
   expected
 * Helpers for parsing auxiluary devices from the device tree
 * New support for AllWinner A64, Cirrus Logic CS4234, Mediatek
   MT6359 Microchip S/PDIF TX and RX controllers, Realtek RT1015P,
   and Texas Instruments J721E, TAS2110, TAS2564 and TAS2764

Merge tag 'selinux-pr-20201012' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux

Pull selinux updates from Paul Moore:
 "A decent number of SELinux patches for v5.10, twenty two in total. The
  highlights are listed below, but all of the patches pass our test
  suite and merge cleanly.

   - A number of changes to how the SELinux policy is loaded and managed
     inside the kernel with the goal of improving the atomicity of a
     SELinux policy load operation.

     These changes account for the bulk of the diffstat as well as the
     patch count. A special thanks to everyone who contributed patches
     and fixes for this work.

   - Convert the SELinux policy read-write lock to RCU.

   - A tracepoint was added for audited SELinux access control events;
     this should help provide a more unified backtrace across kernel and
     userspace.

   - Allow the removal of security.selinux xattrs when a SELinux policy
     is not loaded.

   - Enable policy capabilities in SELinux policies created with the
     scripts/selinux/mdp tool.

   - Provide some "no sooner than" dates for the SELinux checkreqprot
     sysfs deprecation"

09b791d955 powerpc/hv-gpci: Add sysfs files inside hv-gpci device to show cpumask
Patch here adds a cpumask attr to hv_gpci pmu along with ABI documentation.

Primary use to expose the cpumask is for the perf tool which has the
capability to parse the driver sysfs folder and understand the
cpumask file. Having cpumask file will reduce the number of perf command
line parameters (will avoid "-C" option in the perf tool
command line). It can also notify the user which is
the current cpu used to retrieve the counter data.

05f94eb989 power: supply: document current direction
Currently the sign for CURRENT_NOW and CURRENT_AVG is a bit
of a mess. There are basically 3 different ways battery fuel
gauges report the current:

1. uses negative values for discharging and positive values
   for charging
2. uses positive values for discharging and negative values
   for discharging (opposit of 1)
3. only uses positive values

As a result userspace currently cannot use the sign at all in
a generic way. Let's solve the issue by documenting a canonical
way for reporting the data and ensure new drivers follow this
way. Then existing drivers can be fixed on a case-by-case basis.

The 'negative value = battery discharging' has been choosen,
since there are only very few drivers doing it the other way
around.

021da53e65 w1: w1_therm: Add sysfs entries to control conversion time and driver features
The conversion time of common DS18B20 clones deviates from
datasheet specs. Allow adjustment and automatic measure of the
conversion time.

Add 'conv_time' sysfs attribute:
  *read*: Current conversion time in milliseconds.
  *write*:
     '0': Set default conversion time.
     '1': Measure and set the conversion time. Make a
          single temperature conversion, poll and measure
          an actual value. Measured value is increased
          by 20% for temperature drift. A new conversion
          time is returned by reading the same attribute.
     other positive value:
        Set the conversion time in milliseconds.

The setting is active until a resolution change. Then it is reset to
default conversion time for a new resolution.

Add 'features' sysfs attribute to control optional driver settings
per device. Bit masks to read/write (logical OR):
  1: Enable check for conversion success. If byte 6 of
     scratchpad memory is 0xC after conversion, and
     temperature reads 85.00 (powerup value) or 127.94
     (insufficient power) - return a conversion error.

  2: Enable poll for conversion completion. Generate read cycles
     after the conversion start and wait for 1's. In parasite
     power mode this feature is not available.

There are some clones of DS18B20 with fixed 12 bit resolution. Make the
driver verify the resolution by reading back the device after resolution
change.

876611c493 mfd: intel-m10-bmc: Add Intel MAX 10 BMC chip support for Intel FPGA PAC
This patch implements the basic functions of the BMC chip for some Intel
FPGA PCIe Acceleration Cards (PAC). The BMC is implemented using the
Intel MAX 10 CPLD.

This BMC chip is connected to the FPGA by a SPI bus. To provide direct
register access from the FPGA, the "SPI slave to Avalon Master Bridge"
(spi-avmm) IP is integrated in the chip. It converts encoded streams of
bytes from the host to the internal register read/write on the Avalon
bus. So This driver uses the regmap-spi-avmm for register accessing.

0173f525b2 soundwire: sysfs: add slave status and device number before probe
The MIPI DisCo device properties that are read by the driver from
platform firmware, or hard-coded in the driver, should only be
provided as sysfs entries when a driver probes successfully.

However the device status and device number is updated even when there
is no driver present, and hence can be updated when a Slave device is
detected on the bus without being described in platform firmware and
without any driver registered/probed.

As suggested by GregKH, the attribute group for Slave status and
device number is is added by default upon device registration.

Credits to Vinod Koul for the status_show() function, shared in a
separate patch and used as is here. The status table was modified to
remove an unnecessary enum and status_show() is handled in a different
group attribute than what was suggested by Vinod.

ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.

Most of this change is an internal renaming of variables, functions and

Those will be deprecated next year. Add the documentation about it in sysfs

I have grouped those to keep this short.

There are a few late breaking fixes in here that can wait for the
merge window.

of_match_ptr removal and incorrect ACPI binding removal

  is trivial and it breaks ACPI PRP0001 based instantiation.
  Mostly this series is about removing examples that get copied into new
  drivers.

2ce6324ead ACPI: DPTF: Add PCH FIVR participant driver
This driver adds support for Dynamic Platform and Thermal Framework
(DPTF) PCH (Platform Controller Hub) FIVR (Fully Integrated Voltage
Regulator) participant support.

This participant is responsible for exposing platform telemetry and
control for:
	freq_mhz_high_clock
	freq_mhz_low_clock

These attributes are used to get and set PCH FIVR switching frequency
for thermal and radio frequency interference mitigation.

Refer to Documentation/ABI/testing/sysfs-platform-dptf for ABI details.

ACPI methods description used in this driver:
RFC0: This ACPI method to set PCH FIVR switching frequency when FIVR
clock is 19.2MHz or 24MHz. The ACPI method takes a DWORD value.
GFC0: This ACPI method to get PCH FIVR switching frequency when FIVR
clock is 19.2MHz or 24MHz.
RFC1: This ACPI method to set PCH FIVR switching frequency when FIVR
clock is 38.4MHz. The ACPI method takes a DWORD value.
GFC1: This ACPI method to get PCH FIVR switching frequency when FIVR
clock is 38.4MHz.

b854e83101 docs: stable-ABI: Document /sys/kernel/notes
Document the notes file in sysfs as the running vmlinux's .note section
in binary format. Hopefully this helps someone like me realize the
kernel exposes the note section in sysfs in the future. Take the date
from when the file was introduced. It's been a while so presumably this
is stable and not testing material.

dde8ceec9e iio: temperature: mlx90632: Interface to change object ambient temperature
Since object temperature might be different than the sensor temperature
the infrared sensors should provide an interface to inject ambient
temperature. This was in past done via write to ambient temperature
interface (in_temp_ambient_raw), but I think most people did not know
about it. This solution introduces a new iio type of the CALIBAMBIENT
which is hopefully more descriptive and more explicit about the purpose
and capabilities of the sensors.

093749e296 f2fs: support age threshold based garbage collection
There are several issues in current background GC algorithm:
- valid blocks is one of key factors during cost overhead calculation,
so if segment has less valid block, however even its age is young or
it locates hot segment, CB algorithm will still choose the segment as
victim, it's not appropriate.
- GCed data/node will go to existing logs, no matter in-there datas'
update frequency is the same or not, it may mix hot and cold data
again.
- GC alloctor mainly use LFS type segment, it will cost free segment
more quickly.

This patch introduces a new algorithm named age threshold based
garbage collection to solve above issues, there are three steps
mainly:

1. select a source victim:
- set an age threshold, and select candidates beased threshold:
e.g.
 0 means youngest, 100 means oldest, if we set age threshold to 80
 then select dirty segments which has age in range of [80, 100] as
 candiddates;
- set candidate_ratio threshold, and select candidates based the
ratio, so that we can shrink candidates to those oldest segments;
- select target segment with fewest valid blocks in order to
migrate blocks with minimum cost;

2. select a target victim:
- select candidates beased age threshold;
- set candidate_radius threshold, search candidates whose age is
around source victims, searching radius should less than the
radius threshold.
- select target segment with most valid blocks in order to avoid
migrating current target segment.

3. merge valid blocks from source victim into target victim with
SSR alloctor.

Test steps:
- create 160 dirty segments:
 * half of them have 128 valid blocks per segment
 * left of them have 384 valid blocks per segment
- run background GC

Benefit: GC count and block movement count both decrease obviously:

- Before:
  - Valid: 86
  - Dirty: 1
  - Prefree: 11
  - Free: 6001 (6001)

GC calls: 162 (BG: 220)
  - data segments : 160 (160)
  - node segments : 2 (2)
Try to move 41454 blocks (BG: 41454)
  - data blocks : 40960 (40960)
  - node blocks : 494 (494)

IPU: 0 blocks
SSR: 0 blocks in 0 segments
LFS: 41364 blocks in 81 segments

- After:

  - Valid: 87
  - Dirty: 0
  - Prefree: 4
  - Free: 6008 (6008)

GC calls: 75 (BG: 76)
  - data segments : 74 (74)
  - node segments : 1 (1)
Try to move 12813 blocks (BG: 12813)
  - data blocks : 12544 (12544)

9ba3a0aa09 fpga: dfl: create a dfl bus type to support DFL devices
A new bus type "dfl" is introduced for private features which are not
initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these
private features could be handled by separate driver modules.

DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on
enumeration. DFL drivers could be registered on this bus to match these
DFL devices. They are matched by dfl type & feature_id.

4a851d714e fsi: aspeed: Support CFAM reset GPIO
Systems have a line for restting the remote CFAM. This is not part of
the FSI master, but is associated with it, so it makes sense to include
it in the master driver.

This exposes a sysfs interface to reset the cfam, abstracting away the
direction and polarity of the GPIO, as well as the timing of the reset
pulse. Userspace will be blocked until the reset pulse is finished.

The reset is hard coded to be in the range of (900, 1000) us. It was
observed with a scope to regularly be just over 1ms.

If the device tree property is not preset the driver will silently
continue.

086ba2ec16 f2fs-for-5.9-rc1
In this round, we've added two small interfaces, 1) GC_URGENT_LOW mode for
 performance, and 2) F2FS_IOC_SEC_TRIM_FILE ioctl for security. The new GC
 mode allows Android to run some lower priority GCs in background, while new
 ioctl discards user information without race condition when the account is
 removed. In addition, some patches were merged to address latency-related
 issues. We've fixed some compression-related bug fixes as well as edge race
 conditions.
 
 Enhancement:
  - add GC_URGENT_LOW mode in gc_urgent
  - introduce F2FS_IOC_SEC_TRIM_FILE ioctl
  - bypass racy readahead to improve read latencies
  - shrink node_write lock coverage to avoid long latency
 
 Bug fix:
  - fix missing compression flag control, i_size, and mount option
  - fix deadlock between quota writes and checkpoint
  - remove inode eviction path in synchronous path to avoid deadlock
  - fix to wait GCed compressed page writeback
  - fix a kernel panic in f2fs_is_compressed_page
  - check page dirty status before writeback
  - wait page writeback before update in node page write flow
  - fix a race condition between f2fs_write_end_io and f2fs_del_fsync_node_entry
 
 We've added some minor sanity checks and refactored trivial code blocks for
 better readability and debugging information.

25d8d4eeca powerpc updates for 5.9
- Add support for (optionally) using queued spinlocks & rwlocks.
 
  - Support for a new faster system call ABI using the scv instruction on Power9
    or later.
 
  - Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on
    Power10 and future processors, leaving us with no way to implement the
    functionality it requests. This risks breaking userspace, though we believe
    it is unused in practice.
 
  - A bug fix for, and then the removal of, our custom stack expansion checking.
    We now allow stack expansion up to the rlimit, like other architectures.
 
  - Remove the remnants of our (previously disabled) topology update code, which
    tried to react to NUMA layout changes on virtualised systems, but was prone
    to crashes and other problems.
 
  - Add PMU support for Power10 CPUs.
 
  - A change to our signal trampoline so that we don't unbalance the link stack
    (branch return predictor) in the signal delivery path.
 
  - Lots of other cleanups, refactorings, smaller features and so on as usual.

d862a3068e Input: exc3000 - add support to query model and fw_version
Expose model and fw_version via sysfs. Also query the model
in probe to make sure, that the I2C communication with the
device works before successfully probing the driver.

This is a bit complicated, since EETI devices do not have
a sync interface. Sending the commands and directly reading
does not work. Sending the command and waiting for some time
is also not an option, since there might be touch events in
the mean time.

Last but not least we do not cache the results, since this
interface can be used to check the I2C communication is still
working as expected.

c0c419c045 Staging/IIO driver patches for 5.9-rc1
Here is the large set of Staging and IIO driver patches for 5.9-rc1.
 
 Lots of churn here, but overall the size increase in lines added is
 small, while adding a load of new IIO drivers.
 
 Major things in here:
 	- lots and lots of IIO new drivers and frameworks added
 	- IIO driver fixes and updates
 	- lots of tiny coding style cleanups for staging drivers
 	- vc04_services major reworks and cleanups
 
 We had 3 set of drivers move out of staging in this round as well:
 	- wilc1000 wireless driver moved out of staging
 	- speakup moved out of staging
 	- most USB driver moved out of staging
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues.  The last
 few changes here were to resolve reported linux-next issues, and they
 seem to have resolved the problems.

e4a7b2dc35 LEDs changes for 5.9-rc1.
Okay, so... this one is interesting. RGB LEDs are very common, and we
 need to have some kind of support for them. Multicolor is for
 arbitrary set of LEDs in one package, RGB is for LEDs that can produce
 full range of colors. We do not have real multicolor LED that is not
 RGB in the pipeline, so that one is disabled for now.
 
 You can expect this saga to continue with next pull requests.

dd27111e32 Driver core changes for 5.9-rc1
Here is the "big" set of changes to the driver core, and some drivers
 using the changes, for 5.9-rc1.
 
 "Biggest" thing in here is the device link exposure in sysfs, to help
 to tame the madness that is SoC device tree representations and driver
 interactions with it.
 
 Other stuff in here that is interesting is:
 	- device probe log helper so that drivers can report problems in
 	  a unified way easier.
 	- devres functions added
 	- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
 	  incorrect sysfs file permissions
 	- documentation cleanups
 	- ability for debugfs to be present in the kernel, yet not
 	  exposed to userspace.  Needed for systems that want it
 	  enabled, but do not trust users, so they can still use some
 	  kernel functions that were otherwise disabled.
 	- other minor fixes and cleanups
 
 The patches outside of drivers/base/ all have acks from the respective
 subsystem maintainers to go through this tree instead of theirs.
 
 All of these have been in linux-next with no reported issues.

Pull power management updates from Rafael Wysocki:
 "The most significant change here is the extension of the Energy Model
  to cover non-CPU devices (as well as CPUs) from Lukasz Luba.

  There is also some new hardware support (Ice Lake server idle states
  table for intel_idle, Sapphire Rapids and Power Limit 4 support in the
  RAPL driver), some new functionality in the existing drivers (eg. a
  new switch to disable/enable CPU energy-efficiency optimizations in
  intel_pstate, delayed timers in devfreq), some assorted fixes (cpufreq
  core, intel_pstate, intel_idle) and cleanups (eg. cpuidle-psci,
  devfreq), including the elimination of W=1 build warnings from cpufreq
  done by Lee Jones.

  Specifics:

   - Make the Energy Model cover non-CPU devices (Lukasz Luba).

   - Add Ice Lake server idle states table to the intel_idle driver and
     eliminate a redundant static variable from it (Chen Yu, Rafael
     Wysocki).

   - Eliminate all W=1 build warnings from cpufreq (Lee Jones).

   - Add support for Sapphire Rapids and for Power Limit 4 to the Intel
     RAPL power capping driver (Sumeet Pawnikar, Zhang Rui).

   - Fix function name in kerneldoc comments in the idle_inject power
     capping driver (Yangtao Li).

   - Fix locking issues with cpufreq governors and drop a redundant
     "weak" function definition from cpufreq (Viresh Kumar).

   - Rearrange cpufreq to register non-modular governors at the
     core_initcall level and allow the default cpufreq governor to be
     specified in the kernel command line (Quentin Perret).

   - Extend, fix and clean up the intel_pstate driver (Srinivas
     Pandruvada, Rafael Wysocki):

       * Add a new sysfs attribute for disabling/enabling CPU
         energy-efficiency optimizations in the processor.

       * Make the driver avoid enabling HWP if EPP is not supported.

       * Allow the driver to handle numeric EPP values in the sysfs
         interface and fix the setting of EPP via sysfs in the active
         mode.

       * Eliminate a static checker warning and clean up a kerneldoc
         comment.

   - Clean up some variable declarations in the powernv cpufreq driver
     (Wei Yongjun).

   - Fix up the ->enter_s2idle callback definition to cover the case
     when it points to the same function as ->idle correctly (Neal Liu).

   - Rearrange and clean up the PSCI cpuidle driver (Ulf Hansson).

   - Make the PM core emit "changed" uevent when adding/removing the
     "wakeup" sysfs attribute of devices (Abhishek Pandit-Subedi).

   - Add a helper macro for declaring PM callbacks and use it in the MMC
     jz4740 driver (Paul Cercueil).

   - Fix white space in some places in the hibernate code and make the
     system-wide PM code use "const char *" where appropriate (Xiang
     Chen, Alexey Dobriyan).

   - Add one more "unsafe" helper macro to the freezer to cover the NFS
     use case (He Zhe).

   - Change the language in the generic PM domains framework to use
     parent/child terminology and clean up a typo and some comment
     fromatting in that code (Kees Cook, Geert Uytterhoeven).

   - Update the operating performance points OPP framework (Lukasz Luba,
     Andrew-sh.Cheng, Valdis Kletnieks):

       * Refactor dev_pm_opp_of_register_em() and update related drivers.

       * Add a missing function export.

       * Allow disabled OPPs in dev_pm_opp_get_freq().

   - Update devfreq core and drivers (Chanwoo Choi, Lukasz Luba, Enric
     Balletbo i Serra, Dmitry Osipenko, Kieran Bingham, Marc Zyngier):

       * Add support for delayed timers to the devfreq core and make the
         Samsung exynos5422-dmc driver use it.

       * Unify sysfs interface to use "df-" as a prefix in instance
         names consistently.

       * Fix devfreq_summary debugfs node indentation.

       * Add the rockchip,pmu phandle to the rk3399_dmc driver DT
         bindings.

       * List Dmitry Osipenko as the Tegra devfreq driver maintainer.

       * Fix typos in the core devfreq code.

   - Update the pm-graph utility to version 5.7 including a number of
     fixes related to suspend-to-idle (Todd Brandt).

   - Fix coccicheck errors and warnings in the cpupower utility (Shuah
     Khan).

   - Replace HTTP links with HTTPs ones in multiple places (Alexander A.
     Klimov)"

822ef14e9d ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
 to have the code merged through the soc tree as upstream, as the code
 tends to be used across multiple SoCs or has SoC specific drivers itself:
 
  - memory controllers:
      Krzysztof Kozlowski takes ownership of the drivers/memory
      subsystem and its drivers, starting out with a set of cleanup
      patches.
      A larger driver for the Tegra memory controller that was accidentally
      missed for v5.8 is now added.
 
  - reset controllers:
      Only minor updates to drivers/reset this time
 
  - firmware:
      The "turris mox" firmware driver gains support for signed firmware blobs
      The tegra firmware driver gets extended to export some debug information
      Various updates to i.MX firmware drivers, mostly cosmetic
 
  - ARM SCMI/SCPI:
      A new mechanism for platform notifications is added, among a number
      of minor changes.
 
  - optee:
      Probing of the TEE bus is rewritten to better support detection of
      devices that depend on the tee-supplicant user space.
      A new firmware based trusted platform module (fTPM) driver is added
      based on OP-TEE
 
  - SoC attributes:
      A new driver is added to provide a generic soc_device for identifying
      a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
      by probing SoC family specific registers.
      The series also contains some cleanups to the common soc_device code.
 
 There are also a number of updates to SoC specific drivers,
 the main ones are:
 
  - Mediatek cmdq driver gains a few in-kernel interfaces
 
  - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
    support for additional SoC variants
 
  - The Qualcomm GENI core code gains interconnect path voting and
    performance level support, and integrating this into a number of
    device drivers.
 
  - A new driver for Samsung Exynos5800 voltage coupler for
 
  - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
    specific device drivers
 
  - Updates to the TI K3 Ring Accelerator driver

2d02bf835e powerpc/papr_scm: Fetch nvdimm performance stats from PHYP
Update papr_scm.c to query dimm performance statistics from PHYP via
H_SCM_PERFORMANCE_STATS hcall and export them to user-space as PAPR
specific NVDIMM attribute 'perf_stats' in sysfs. The patch also
provide a sysfs ABI documentation for the stats being reported and
their meanings.

During NVDIMM probe time in papr_scm_nvdimm_init() a special variant
of H_SCM_PERFORMANCE_STATS hcall is issued to check if collection of
performance statistics is supported or not. If successful then a PHYP
returns a maximum possible buffer length needed to read all
performance stats. This returned value is stored in a per-nvdimm
attribute 'stat_buffer_len'.

The layout of request buffer for reading NVDIMM performance stats from
PHYP is defined in 'struct papr_scm_perf_stats' and 'struct
papr_scm_perf_stat'. These structs are used in newly introduced
drc_pmem_query_stats() that issues the H_SCM_PERFORMANCE_STATS hcall.

The sysfs access function perf_stats_show() uses value
'stat_buffer_len' to allocate a buffer large enough to hold all
possible NVDIMM performance stats and passes it to
drc_pmem_query_stats() to populate. Finally statistics reported in the
buffer are formatted into the sysfs access function output buffer.
