a7fd43d950 dt-bindings: ipmi: Add optional SerIRQ property to ASPEED KCS devices 
Allocating IO and IRQ resources to LPC devices is in-theory an operation
for the host, however ASPEED don't appear to expose this capability
outside the BMC (e.g. SuperIO). Instead, we are left with BMC-internal
registers for managing these resources, so introduce a devicetree
property for KCS devices to describe SerIRQ properties.

e880275ccf dt-bindings: ipmi: Convert ASPEED KCS binding to schema 
Given the deprecated binding, improve the ability to detect issues in
the platform devicetrees. Further, a subsequent patch will introduce a
new interrupts property for specifying SerIRQ behaviour, so convert
before we do any further additions.

d72cd4ad41 SCSI misc on 20210428 
This series consists of the usual driver updates (ufs, target, tcmu,
 smartpqi, lpfc, zfcp, qla2xxx, mpt3sas, pm80xx).  The major core
 change is using a sbitmap instead of an atomic for queue tracking.

35655ceb31 Here's a collection of largely clk driver updates for the merge window. The 
usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and
 Rockchip, but it feels pretty light on commits. There's only one real commit to
 the framework core and that's to consolidate code. Otherwise the diffstat is
 dominated by many Qualcomm clk driver patches that modernize the driver for the
 proper way of speciying clk parents. That's shifting data around, which could
 subtly break things so I'll be on the lookout for fixes.
 
 New Drivers:
  - Proper clk driver for Mediatek MT7621 SoCs
  - Support for the clock controller on the new Rockchip rk3568
 
 Updates:
  - Simplify Zynq Kconfig dependencies
  - Use clk_hw pointers in socfpga driver
  - Cleanup parent data in qcom clk drivers
  - Some cleanups for rk3399 modularization
  - Fix reparenting of i.MX UART clocks by initializing only the ones
    associated to stdout
  - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
  - Make i.MX LPCG and SCU clocks return on registering failure
  - Kernel doc fixes
  - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
  - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
  - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U
  - Sigma-delta modulation on Allwinner V3s audio PLL

16b3d0cf5b Scheduler updates for this cycle are: 
- Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and debugfs interfaces
    to a unified debugfs interface.
 
  - Signals: Allow caching one sigqueue object per task, to improve performance & latencies.
 
  - Improve newidle_balance() irq-off latencies on systems with a large number of CPU cgroups.
 
  - Improve energy-aware scheduling
 
  - Improve the PELT metrics for certain workloads
 
  - Reintroduce select_idle_smt() to improve load-balancing locality - but without the previous
    regressions
 
  - Add 'scheduler latency debugging': warn after long periods of pending need_resched. This
    is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature,
    or the use of the resched_latency_warn_ms=xx boot parameter.
 
  - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix remaining
    balance_push() vs. hotplug holes/races
 
  - PSI fixes, plus allow /proc/pressure/ files to be written by CAP_SYS_RESOURCE tasks as well
 
  - Fix/improve various load-balancing corner cases vs. capacity margins
 
  - Fix sched topology on systems with NUMA diameter of 3 or above
 
  - Fix PF_KTHREAD vs to_kthread() race
 
  - Minor rseq optimizations
 
  - Misc cleanups, optimizations, fixes and smaller updates

Merge tag 'printk-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
   result, the access to the buffer is fully lockless now.

   Note that printk() itself still uses locks because it tries to flush
   the messages to the console immediately. Also the per-CPU temporary
   buffers are still there because they prevent infinite recursion and
   serialize backtraces from NMI. All this is going to change in the
   future.

 - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
   removal.

 - Make bstr_printf() aware that %pf and %pF formats could deference the
   given pointer.

 - Show also page flags by %pGp format.

 - Clarify the documentation for plain pointer printing.

 - Do not show no_hash_pointers warning multiple times.

 - Update Senozhatsky email address.

 - Some clean up.

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.
 
 - various other small fixes and improvements all over the place.

Merge tag 's390-5.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - 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.

 - various other small fixes and improvements all over the place.

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull network filesystem helper library updates from David Howells:
 "Here's a set of patches for 5.13 to begin the process of overhauling
  the local caching API for network filesystems. This set consists of
  two parts:

  (1) Add a helper library to handle the new VM readahead interface.

      This is intended to be used unconditionally by the filesystem
      (whether or not caching is enabled) and provides a common
      framework for doing caching, transparent huge pages and, in the
      future, possibly fscrypt and read bandwidth maximisation. It also
      allows the netfs and the cache to align, expand and slice up a
      read request from the VM in various ways; the netfs need only
      provide a function to read a stretch of data to the pagecache and
      the helper takes care of the rest.

  (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
      facility to do async DIO to transfer data to/from the netfs's
      pages, rather than using readpage with wait queue snooping on one
      side and vfs_write() on the other. It also uses less memory, since
      it doesn't do buffered I/O on the backing file.

      Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
      available to be read from the cache. Whilst this is an improvement
      from the bmap interface, it still has a problem with regard to a
      modern extent-based filesystem inserting or removing bridging
      blocks of zeros. Fixing that requires a much greater overhaul.

  This is a step towards overhauling the fscache API. The change is
  opt-in on the part of the network filesystem. A netfs should not try
  to mix the old and the new API because of conflicting ways of handling
  pages and the PG_fscache page flag and because it would be mixing DIO
  with buffered I/O. Further, the helper library can't be used with the
  old API.

  This does not change any of the fscache cookie handling APIs or the
  way invalidation is done at this time.

  In the near term, I intend to deprecate and remove the old I/O API
  (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
  fscache_write_page() and fscache_uncache_page()) and eventually
  replace most of fscache/cachefiles with something simpler and easier
  to follow.

  This patchset contains the following parts:

   - Some helper patches, including provision of an ITER_XARRAY iov
     iterator and a function to do readahead expansion.

   - Patches to add the netfs helper library.

   - A patch to add the fscache/cachefiles kiocb API.

   - A pair of patches to fix some review issues in the ITER_XARRAY and
     read helpers as spotted by Al and Willy.

  Jeff Layton has patches to add support in Ceph for this that he
  intends for this merge window. I have a set of patches to support AFS
  that I will post a separate pull request for.

  With this, AFS without a cache passes all expected xfstests; with a
  cache, there's an extra failure, but that's also there before these
  patches. Fixing that probably requires a greater overhaul. Ceph also
  passes the expected tests.

  I also have patches in a separate branch to tidy up the handling of
  PG_fscache/PG_private_2 and their contribution to page refcounting in
  the core kernel here, but I haven't included them in this set and will
  route them separately"

Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the most recent upstream
  revision including (but not limited to) new material introduced in the
  6.4 version of the spec, update message printing in the ACPI-related
  code, address a few issues and clean up code in a number of places.

  Specifics:

   - Update ACPICA code in the kernel to upstream revision 20210331
     including the following changes:

      * Add parsing for IVRS IVHD 40h and device entry F0h (Alexander
        Monakov).

        Brucker).

      * IORT: Updates for revision E.b (Shameer Kolothum).

   - Rearrange message printing in ACPI-related code to avoid using the
     ACPICA's internal message printing macros outside ACPICA and do
     some related code cleanups (Rafael Wysocki).

   - Modify the device enumeration code to turn off all of the unused
     ACPI power resources at the end (Rafael Wysocki).

   - Change the ACPI power resources handling code to turn off unused
     ACPI power resources without checking their status which should not
     be necessary by the spec (Rafael Wysocki).

   - Add empty stubs for CPPC-related functions to be used when
     CONFIG_ACPI_CPPC_LIB is not set (Rafael Wysocki).

   - Simplify device enumeration code (Rafael Wysocki).

   - Change device enumeration code to use match_string() for string
     matching (Andy Shevchenko).

   - Modify irqresource_disabled() to retain the resouce flags that have
     been set already (Angela Czubak).

   - Add native backlight whitelist entry for GA401/GA502/GA503 (Luke
     Jones).

   - Modify the ACPI backlight driver to let the native backlight
     handling take over on hardware-reduced systems (Hans de Goede).

   - Introduce acpi_dev_get() and switch over the ACPI core code to
     using it (Andy Shevchenko).

   - Use kobj_attribute as callback argument instead of a local struct
     type in the CPPC linrary code (Nathan Chancellor).

   - Drop unneeded initializatio of a static variable from the ACPI
     processor driver (Tian Tao).

   - Drop unnecessary local variable assignment from the ACPI APEI code
     (Colin Ian King).

47080f2286 hwmon updates for v5.13 
The most notable change is the removal of the amd_energy driver. It was
 rendered all but unusable by making its attributes privileged-only to work
 around a security issue. A suggested remedy was rejected by AMD, so the
 only real solution was to remove the driver. For the future, we'll have
 to make sure that no privileged-access-only drivers are accepted into the
 hwmon subsystem in the first place. The hwmon ABI document was updated
 accordingly.
 
 Other changes:
 
 PMBus drivers:
 - Added driver for MAX15301
 - Added driver for BluTek BPA-RS600
 - Added driver for fsp-3y PSUs and PDUs
 - Added driver for Infineon IR36021
 - Added driver for ST STPDDC60
 - Added support for TI TPS53676 to tps53679 driver
 - Introduced PMBUS symbol namespace
   This was made necessary by a suggestion to use its exported functions
   from outside the hwmon subsystem.
 - Minor improvements and bug fixes
 
 New drivers:
 - Driver for NZXT Kraken X42/X52/X62/X72
 
 Driver enhancements:
 - Added support for Intel D5005 to intel-m10-bmc-hwmon driver
 - Added support for NCT6686D to nct6683 driver
 
 Other:
 - Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
 - Added support for fan drawers capability and present registers to mlxreg-fan
   driver
 - Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
 - Replaced snprintf in show functions with sysfs_emit
   Done with coccinelle script for all drivers to preempt endless per-driver
   submissions of the same change.
 - Use kobj_to_dev()
   Another coccinelle based change to preempt endless per-driver submissions
   of the same change.
 - Various minor fixes and improvements

0c85556318 ARM: platform support for Apple M1 
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 but it boots and can use framebuffer and serial console over a special
 USB cable.
 
 Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

6b0fbc540c ARM: platform support for Nuvoton WPCM450 
The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
 that remains in use on Supermicro X9 server boards among others. Support
 gets added for a particular server board using this SoC along with the
 basic platform bringup.
 
 As the platform is a predecessor to the npcm7xx platform we already
 support, it is added to the same directory, despite using a different
 name. It also seems to be related to the older w90x900/nuc9xx platform
 that was removed last year.

f7857bf374 ARM: devicetree changes for 5.13 
There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450
 have separate branches because they are new SoC families that require
 changes outside of device tree files. The other four are variations of
 already supported chips and get merged through this branch:
 
  - STMicroelectronics STM32H750 is one of many variants of STM32
    microcontrollers based on the Cortex-M7 core. This is particularly
    notable since we rarely add support for new MMU-less chips
    these days. In this case, the board that gets added along with
    the platform is not a SoC reference platform but the "Art Pi"
    (https://art-pi.gitee.io/website/) machine that was originally design
    for the RT-Thread RTOS.
 
  - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial
    SoC family, using two Cortex-A72 and four Cortex-A53 cores. It
    gets added along with its reference board, the "NXP i.MX8QuadMax
    Multisensory Enablement Kit".
 
  - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c)
    that is used in some Chromebooks and Windows laptops. Only a reference
    board is added for the moment.
 
  - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial
    control, motor control, remote IO, IoT gateway etc., similar to the
    older AM65x family. Two reference machines are added alongside.
 
 Among the newly added machines, there is a very clear skew towards 64-bit
 machines now, with 12 32-bit machines compared to 23 64-bit machines. The
 full list sorted by SoC is:
 
  - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
  - Allwinner A10: Topwise A721 Tablet
  - Amlogic GXL: MeCool KII TV box
  - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
  - Broadcom BCM4908: TP-Link Archer C2300 V1 router
  - MStar SSD202D: M5Stack UnitV2 camera
  - Marvell Armada 38x: ATL-x530 ethernet switch
  - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311,
    Asus Flip CM3, Asus Detachable CM3

  - NXP i.MX7: reMarkable Tablet
  - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini

  - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM,
    EDIMM2.2 Starter Kit, Carrier, SOM
  - TI AM65: Siemens SIMATIC IOT2050 gateway
 
 There is notable work going into extending already supported machines
 and SoCs:
 
  - ASpeed AST2500
  - Allwinner A23, A83t, A31, A64, H6
  - Amlogic G12B
  - Broadcom BCM4908
  - Marvell Armada 7K/8K/CN91xx
  - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
  - NXP i.MX8Q, i.MX8MM, i.MX8MP
  - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
  - Renesas R-Car M3, V3U
  - Rockchip RK3328, RK3399
  - STEricsson U8500
  - STMicroelectronics STM32MP141
  - Samsung Exynos 4412
  - TI K3-AM65, K3-J7200
  - TI OMAP3
 
 Among the treewide cleanups and bug fixes, two parts stand out:
 
  - There are a number of cleanups for issues pointed out by 'make
    dtbs_check' this time, and I expect more to come in the future as we
    increasingly check for regressions.
 
  - After a change to the MMC subsystem that can lead to unpredictable
    device numbers, several platforms add 'aliases' properties for these
    to give each MMC controller a fixed number.

ef12441243 USB/Thunderbolt patches for 5.13-rc1 
Here is the big set of USB and Thunderbolt driver updates for 5.13-rc1.
 
 Lots of little things in here, with loads of tiny fixes and cleanups
 over these drivers, as well as these "larger" changes:
 	- thunderbolt updates and new features added
 	- xhci driver updates and split out of a mediatek-specific xhci
 	  driver from the main xhci module to make it easier to work

Here is the big set of tty and serial driver updates for 5.13-rc1.
 
 Actually busy this release, with a number of cleanups happening:
 	- much needed core tty cleanups by Jiri Slaby
 	- removal of unused and orphaned old-style serial drivers.  If
 	  anyone shows up with this hardware, it is trivial to restore
 	  these but we really do not think they are in use anymore.
 	- fixes and cleanups from Johan Hovold on a number of termios
 	  setting corner cases that loads of drivers got wrong as well
 	  as removing unneeded code due to tty core changes from long
 	  ago that were never propagated out to the drivers
 	- loads of platform-specific serial port driver updates and
 	  fixes
 	- coding style cleanups and other small fixes and updates all
 	  over the tty/serial tree.
 
 All of these have been in linux-next for a while now with no reported

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.

31a24ae89c arm64 updates for 5.13: 
- MTE asynchronous support for KASan. Previously only synchronous
   (slower) mode was supported. Asynchronous is faster but does not allow
   precise identification of the illegal access.
 
 - Run kernel mode SIMD with softirqs disabled. This allows using NEON in
   softirq context for crypto performance improvements. The conditional
   yield support is modified to take softirqs into account and reduce the
   latency.
 
 - Preparatory patches for Apple M1: handle CPUs that only have the VHE
   mode available (host kernel running at EL2), add FIQ support.
 
 - arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers, new
   functions for the HiSilicon HHA and L3C PMU, cleanups.
 
 - Re-introduce support for execute-only user permissions but only when
   the EPAN (Enhanced Privileged Access Never) architecture feature is
   available.
 
 - Disable fine-grained traps at boot and improve the documented boot
   requirements.
 
 - Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).
 
 - Add hierarchical eXecute Never permissions for all page tables.
 
 - Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
   to control which PAC keys are enabled in a particular task.
 
 - arm64 kselftests for BTI and some improvements to the MTE tests.
 
 - Minor improvements to the compat vdso and sigpage.
 
 - Miscellaneous cleanups.

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:

 - MTE asynchronous support for KASan. Previously only synchronous
   (slower) mode was supported. Asynchronous is faster but does not
   allow precise identification of the illegal access.

 - Run kernel mode SIMD with softirqs disabled. This allows using NEON
   in softirq context for crypto performance improvements. The
   conditional yield support is modified to take softirqs into account
   and reduce the latency.

 - Preparatory patches for Apple M1: handle CPUs that only have the VHE
   mode available (host kernel running at EL2), add FIQ support.

 - arm64 perf updates: support for HiSilicon PA and SLLC PMU drivers,
   new functions for the HiSilicon HHA and L3C PMU, cleanups.

 - Re-introduce support for execute-only user permissions but only when
   the EPAN (Enhanced Privileged Access Never) architecture feature is
   available.

 - Disable fine-grained traps at boot and improve the documented boot
   requirements.

 - Support CONFIG_KASAN_VMALLOC on arm64 (only with KASAN_GENERIC).

 - Add hierarchical eXecute Never permissions for all page tables.

 - Add arm64 prctl(PR_PAC_{SET,GET}_ENABLED_KEYS) allowing user programs
   to control which PAC keys are enabled in a particular task.

 - arm64 kselftests for BTI and some improvements to the MTE tests.

 - Minor improvements to the compat vdso and sigpage.

 - Miscellaneous cleanups.

64f8e73de0 Support for enhanced split lock detection: 
Newer CPUs provide a second mechanism to detect operations with lock
   prefix which go accross a cache line boundary. Such operations have to
   take bus lock which causes a system wide performance degradation when
   these operations happen frequently.
 
   The new mechanism is not using the #AC exception. It triggers #DB and is
   restricted to operations in user space. Kernel side split lock access can
   only be detected by the #AC based variant. Contrary to the #AC based
   mechanism the #DB based variant triggers _after_ the instruction was
   executed. The mechanism is CPUID enumerated and contrary to the #AC
   version which is based on the magic TEST_CTRL_MSR and model/family based
   enumeration on the way to become architectural.
