* start adding support for qca4019 chip
ath9k
* add device ID for Toshiba WLM-20U2/GN-1080
* allow more than one interface on DFS channels
The icn, act2000 and pcbit drivers are all for very old hardware,
and it is highly unlikely that anyone is actually still using them
on modern kernels, if at all.
All three drivers apparently are for hardware that predates PCI
being the common connector, as they are ISA-only and active
PCI ISDN cards were widely available in the 1990s.
Looking through the git logs, it I cannot find any indication of a
patch to any of these drivers that has been tested on real hardware,
only cleanups or global API changes.

Although most of USB devices are hot-plug's, there are still some devices
are hard wired on the board, eg, for HSIC and SSIC interface USB devices.
If these kinds of USB devices are multiple functions, and they can supply
other interfaces like i2c, gpios for other devices, we may need to
describe these at device tree.
In this commit, it uses "reg" in dts as physical port number to match
the phyiscal port number decided by USB core, if they are the same,
then the device node is for the device we are creating for USB core.

Currently, network /system cross-timestamping is performed in the
PTP_SYS_OFFSET ioctl. The PTP clock driver reads gettimeofday() and
the gettime64() callback provided by the driver. The cross-timestamp
is best effort where the latency between the capture of system time
(getnstimeofday()) and the device time (driver callback) may be
significant.
The getcrosststamp() callback and corresponding PTP_SYS_OFFSET_PRECISE
ioctl allows the driver to perform this device/system correlation when
for example cross timestamp hardware is available. Modern Intel
systems can do this for onboard Ethernet controllers using the ART
counter. There is virtually zero latency between captures of the ART
and network device clock.
The capabilities ioctl (PTP_CLOCK_GETCAPS), is augmented allowing
applications to query whether or not drivers implement the
getcrosststamp callback, providing more precise cross timestamping.

This reverts commit 82c2ffeb21 ("[media] tvp5150: document input
connectors DT bindings") since the DT binding is too device driver
specific and should instead be more generic and use the bindings
in Documentation/devicetree/bindings/display/connector/ and linked
to the tvp5150 using the OF graph port and endpoints.
There are still ongoing discussions about how the input connectors
will be supported by the Media Controller framework so until that
is settled, it is better to revert the connectors portion of the
bindings to avoid known to be broken bindings docs to hit mainline.

The DSI driver is currently unaware of how the DSI physical data lanes
are mapped to the logical lanes provided by the DSI controller.
Create a DT binding "qcom,data-lane-map" that provides this information
on a given platform.
The MSM DSI controller is restricted in terms of what all mappings
it can support. The lane polarity is fixed for all the lanes, the clock
lanes are fixed, and the data lanes can be swapped among each other only
for a few combinations. Apply these restrictions when we parse the DT
data.

This changes how the used gpios are stored (i.e. a struct gpio_descs
instead of two struct gpio_desc) and as with >2 gpios the states are
numbered differently the function rotary_encoder_get_state returns
unencoded numbers instead of grey encoded numbers before. The latter has
some implications on how the returned value is used and so the change is
bigger than one might expect at first.

Pull Allwinner clk updates from Maxime Ripard:
Allwinner clocks additions for 4.6
A bunch of things, mostly:
- Finally switched everything over to OF_CLK_DECLARE, which should remove
orphans clocks entirely
- Reworked the clk-factors to be able to add new parameters
- Improved the error reporting
- A bunch of new clocks for new SoCs.

This patch restructures the DMA bus settings and this is done
by introducing a new platform structure used for programming
the AXI Bus Mode Register inside the DMA module.
This structure can be populated from device-tree as documented in the
binding txt file.
After initializing the DMA, the AXI register can be optionally tuned
for platform drivers based.
This patch also reworks some parameters to make coherent the DMA
configuration now that AXI register is introduced.
For example, the burst_len is managed by using the mentioned axi
support above; so the snps,burst-len parameter has been removed.
It makes sense to provide the AAL parameter from DT to Address-Aligned
Beats inside the Register0 and review the PBL settings when initialize
the engine.
For PCI glue, rebuilding the story of this setting, it
was added to align a configuration so not for fixing some
known problem. No issue raised after this patch.
It is safe to use the default burst length instead of
tuning it to the maximum value

Good to see several new contributors in this set - and more generally a
number of new 'faces' over this whole cycle.
Staging movements
* hmc5843
- out of staging.
* periodic RTC trigger
- driver dropped. This is an ancient driver (brings back some memories ;)
that was always somewhat of a bodge. Originally there was a driver that
never went into mainline that supported large numbers of periodict timers
on the PXA270 via this route. Discussions to have a generic periodic
timer subsystem never went anywhere. At the time RTC periodic
interrupts were real - now they are emulated using high resolution
timers so with the HRT driver this has become pointless.
New device support
* mpu6050 driver
- Add support for the mpu6500.
* TI tpl0102 potentiometer
- new driver.
* Vybrid SoC DAC
- new driver. The ADC on this SoC has been supported for a while, this
adds a separate driver for the DAC.
New Features
* hmc5844
- Attributes to configure the bias current (typically part of a self test)
This could be done before via a somewhat obscure custom interface.
This at least makes it easy to tell what is going on.
- Document all custom attributes.
* mpu6050
- Add support for calibration offset control and readback.
* ms5611
- power regulator support. This is always one that gets added the
first time someone has a board that needs it. Here it was needed,
hence it was added.
Cleanups / minor fixes
* tree wide
- clean up all the myriad different return values in response to a
failure of i2c_check_functionality. After discussions everyone seemed
happy wiht -EOPNOTSUPP which seems to describe the situation well.
I encouraged a tree wide cleanup to set a good example in future for
this.
* core
- Typos in the iio_event_spec documentation in iio.h
* afe4403
- select REGMAP_SPI to avoid dependency issues
- mark suspend/resume as __maybe_unused to avoid warnings
* afe4404
- mark suspend/resume as __maybe_unused to avoid warnings
* atlas-ph-sensor
- switch the regmap cache type from linear to rbtree to gain reading of
registers on initial startup. It's not immediately obvious, but
regmap flat is meant for high performances cases so doesn't read these
registers.
- use regmap_bulk_read in one case where it was using
i2c_smbus_read_i2c_block_data directly (unlike everything else that was
through regmap).
* ina2xx
- stype cleanups (lots of them!)
* isl29018
- Get the struct device back from regmap rather than storing another
copy of it in the private data. This cleanup makes sense in a number
of other drivers so patches may well follow.
* mpu6050
- style cleanups (lots of them!)
- improved return value handling
- use usleep_range to avoid the usual issues with very short msleeps.
- add some missing documentation.
* ms5611

On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The
ADPLLs have several dividers and muxes controlled by a shared
control register for each PLL.
Note that for the clocks to work as device drivers for booting on
dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall
levels to postcore_initcall" that has already been merged.
Also note that this patch does not implement clk_set_rate for the
PLL, that will be posted later on when available.

The existing KVM_CREATE_SPAPR_TCE only supports 32bit windows which is not
enough for directly mapped windows as the guest can get more than 4GB.
This adds KVM_CREATE_SPAPR_TCE_64 ioctl and advertises it
via KVM_CAP_SPAPR_TCE_64 capability. The table size is checked against
the locked memory limit.
Since 64bit windows are to support Dynamic DMA windows (DDW), let's add
@bus_offset and @page_shift which are also required by DDW.

B.A.T.M.A.N. V. Its implementation started quite some years ago,
but due to the big changes being introduced it took a while to be
discussed, designed, worked, re-worked, tested and debugged (well,
we're never done with the latest). The entire operation has
basically been a team work involving all the core contributors
together with other people interested in the project.
The new protocol is divided into two main subcomponents, called
respectively ELP and OGMv2. The former is in charge of
dealing with the neighbour discovery and link quality estimation,
while the latter implements the algorithm that spreads the
metrics around the network and computes optimal paths.
The biggest change introduced with B.A.T.M.A.N. V is the new
metric: the protocol won't rely on packet loss anymore, but it
will use the estimated throughput extracted directly from the
wifi driver (when available) by querying cfg80211.
Batman-adv will also send some unicast probing packets when
an interface is not used for payload traffic to make sure that
such values are current.
The new protocol can be compiled-in or not like other
features we have and when selected will pull in CFG80211 as
dependency for the reason described above.
Thanks to the big work brought up in the past by Marek Lindner,
batman-adv can easily deal several protocol implementations,
therefore compiling in this new version does not exclude the
older.
This means that the user is offered the option to choose
the protocol when creating the mesh interface (default is the
old one to keep backward compatibility).
Along with the protocol there are some sysfs knobs that are
introduced to fine tune some of its behaviours, but users
are recommended to keep the default values unless they know
what they are doing.
The last patch is about advertising our own patchwork platform
(thanks to Sven Eckelmann for having set that up!) in the
MAINTAINERS file.

This patch adds a exynos5420 driver data to support mic_bypass
option to bypass the mic from display out path.
The mic(Mobile image compressor) compresses RGB data from fimd
and send the compressed data to the mipi dsi.
The bypass option can be founded from system register and the bit
is 11. The option bit has been introduced since exynos5420. The
only difference between exynos5250 and exynos5420/exynos5422 is
existence of the bit. Until the MIC is defined and enabled from
device tree, the bypass mic will be default option.

This patch supports mipi dsi for exynos5422. The dsi register
offsets of the exynos5422 are similar with exynos5433. However,
the values of the registers are quite different from the
exynos5433. For example, the exynos5422 uses sw reset like
previous chips.

Most newer Rockchip SoCs provide the possibility to use a usb-phy
as passthrough for the debug uart (uart2), making it possible to
for example get console output without needing to open the device.
This patch adds an early_initcall to enable this functionality
conditionally via the commandline and also disables the corresponding
usb controller in the devicetree.
Currently only data for the rk3288 is provided, but at least the
rk3188 and arm64 rk3368 also provide this functionality and will be
enabled later.
On a spliced usb cable the signals are tx on white wire(D+) and
rx on green wire(D-).
The one caveat is that currently the reconfiguration of the phy
happens as early_initcall, as the code depends on the unflattened
devicetree being available. Everything is fine if only a regular
console is active as the console-replay will happen after the
reconfiguation. But with earlycon active output up to smp-init
currently will get lost.
The phy is an optional property for the connected dwc2 controller,
so we still provide the phy device but fail all phy-ops with -EBUSY
to make sure the dwc2 does not try to transmit anything on the
repurposed phy.

This parameter can be set individually on each interface and
allows the configuration of the elp interval for the link
quality measurements during runtime. Usually it is desirable
to set it to a higher (= slower) value on interfaces which
have a more static characteristic (e.g. wired interfaces)
or very dense neighbourhoods to reduce overhead.

This commit adds the base Device Tree files for the Armada 7K and 8K
SoCs, as well as the Armada 8040 DB board.
The Armada 7020, 7040 (7K family) and 8020, 8040 (8K family) are
composed of:
- An AP806 block that contains the CPU core and a few basic
peripherals. The AP806 is available in dual core configurations
(used in 7020 and 8020) and quad core configurations (used in 8020
and 8040).
- One or two CP110 blocks that contain all the high-speed interfaces
(SATA, PCIe, Ethernet, etc.). The 7K family chips have one CP110,
and the 8K family chips have two CP110, giving them twice the
number of HW interfaces.
In order to represent this from a Device Tree point of view, this
commit creates the following hierarchy:
* armada-ap806.dtsi - definitions common to dual/quad ap806
* armada-ap806-dual.dtsi - description of the two CPUs
* armada-7020.dtsi - description of the 7020 SoC
* armada-8020.dtsi - description of the 8020 SoC
* armada-ap806-quad.dtsi - description of the four CPUs
* armada-7040.dtsi - description of the 7040 SoC
* armada-7040-db.dts - description of the 7040 board
* armada-8040.dtsi - description of the 8040 SoC
The CP110 blocks are not described yet, and will be part of future
patch series.

Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.
By documenting these compat stings they may be used in DTSs shipped, for
example as part of ROMs. They must be used in conjunction with the Gen2
fallback compat string. At this time there are no known differences between
the r8a779[234] IP blocks and that implemented by the driver for the Gen2
fallback compat string. Thus there is no need to update the driver as the
use of the Gen2 fallback compat string will activate the correct code in
the current driver while leaving the option for r8a779[234]-specific driver
code to be activated in an updated driver should the need arise.

Add fallback compatibility string for R-Car Gen 1 and Gen2.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 1 and Gen 2. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7779 is older than r8a7778 but that doesn't imply that the latter is a
descendant of the former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Currently, all ipv6 addresses are flushed when the interface is configured
down, including global, static addresses:
$ ip -6 addr show dev eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
inet6 2100:1::2/120 scope global
valid_lft forever preferred_lft forever
inet6 fe80::e0:f9ff:fe79:34bd/64 scope link
valid_lft forever preferred_lft forever
$ ip link set dev eth1 down
$ ip -6 addr show dev eth1
<< nothing; all addresses have been flushed>>
Add a new sysctl to make this behavior optional. The new setting defaults to
flush all addresses to maintain backwards compatibility. When the set global
addresses with no expire times are not flushed on an admin down. The sysctl
is per-interface or system-wide for all interfaces
$ sysctl -w net.ipv6.conf.eth1.keep_addr_on_down=1
or
$ sysctl -w net.ipv6.conf.all.keep_addr_on_down=1
Will keep addresses on eth1 on an admin down.
$ ip -6 addr show dev eth1

Drivers/devices without their own rate control algorithm can get the
information what rates they should use from either the radiotap header of
injected frames or from the rate control algorithm. But the parsing of the
legacy rate information from the radiotap header was removed in commit
e6a9854b05 ("mac80211/drivers: rewrite the rate control API").
The removal of this feature heavily reduced the usefulness of frame
injection when wanting to simulate specific transmission behavior. Having
rate parsing together with MCS rates and retry support allows a fine
grained selection of the tx behavior of injected frames for these kind of
tests.

Some qcom based bootloaders identify the dtb blob based on a set
of device properties like SoC, platform, PMIC, and revisions of
those components. In downstream kernels, these values are added
to the different component dtsi files (i.e. pmic dtsi file, SoC
dtsi file, board dtsi file, etc.) via qcom specific DT
properties. The dtb files are parsed by a program called dtbTool
that picks out these properties and creates a table of contents
binary blob with the property information and some offsets into
the concatenation of all the dtbs (termed a QCDT image).
The suggestion is to do this via the board compatible string
instead, because these qcom specific properties are never used by
the kernel. Add a document describing the format of the
compatible string that encodes all this information that's
currently encoded in the qcom,{msm-id,board-id,pmic-id}
properties in downstream devicetrees. Future bootloaders may be
updated to look at the compatible field instead of looking for
the table of contents image. For non-updateable bootloaders, a
new dtbTool program will parse the compatible string and generate
a QCDT image from it.

master which makes the RTC usable. The driver is not supposed to work
with anything else.
The driver uses the standard MicroWire half-duplex transfer timing.
Master output is set on low clock and sensed by the RTC on the rising
edge. Master input is set by the RTC on the trailing edge and is sensed

Add the dt bindings for HiSi SAS controller v2 HW.
The main difference in the controller from dt perspective is
interrupts. The v2 controller does not have dedicated fatal and
broadcast interrupts - they are multiplexed on the channel interrupt.
Each SAS v2 controller can issue upto 64 commands (or connection
requests) on the system bus without waiting for a response - this is
know as am-max-transmissions. In hip06, sas controller #1 has a
limitation that it has to limit am-max-transmissions to 32 - this
limitation is due to chip system bus design. It is not anticipated that
any future chip incorporating v2 controller will have such a limitation.

It may be useful to debug writes to the readonly sections of memory,
so provide a cmdline "rodata=off" to allow for this. This can be
expanded in the future to support "log" and "write" modes, but that
will need to be architecture-specific.
This also makes KDB software breakpoints more usable, as read-only
mappings can now be disabled on any kernel.

Add IMA policy support for measuring/appraising the kexec image and
initramfs. Two new IMA policy identifiers KEXEC_KERNEL_CHECK and
KEXEC_INITRAMFS_CHECK are defined.
Example policy rules:
measure func=KEXEC_KERNEL_CHECK
appraise func=KEXEC_KERNEL_CHECK appraise_type=imasig
measure func=KEXEC_INITRAMFS_CHECK
appraise func=KEXEC_INITRAMFS_CHECK appraise_type=imasig
Moving the enumeration to the vfs layer simplified the patches, allowing
the IMA changes, for the most part, to be separated from the other
changes. Unfortunately, passing either a kernel_read_file_id or a
ima_hooks enumeration within IMA is messy.
Option 1: duplicate kernel_read_file enumeration in ima_hooks
enum kernel_read_file_id {
...
READING_KEXEC_IMAGE,
READING_KEXEC_INITRAMFS,
READING_MAX_ID
enum ima_hooks {
...
KEXEC_KERNEL_CHECK
KEXEC_INITRAMFS_CHECK
Option 2: define ima_hooks as extension of kernel_read_file
eg: enum ima_hooks {
FILE_CHECK = READING_MAX_ID,
MMAP_CHECK,
In order to pass both kernel_read_file_id and ima_hooks values, we
would need to specify a struct containing a union.
struct caller_id {
union {
enum ima_hooks func_id;
enum kernel_read_file_id read_id;
};
};
Option 3: incorportate the ima_hooks enumeration into kernel_read_file_id,
perhaps changing the enumeration name.
For now, duplicate the new READING_KEXEC_IMAGE/INITRAMFS in the ima_hooks.
Changelog v4:
- replaced switch statement with a kernel_read_file_id to an ima_hooks
id mapping array - Dmitry
- renamed ima_hook tokens KEXEC_CHECK and INITRAMFS_CHECK to
KEXEC_KERNEL_CHECK and KEXEC_INITRAMFS_CHECK respectively - Dave Young

Seting X86_CR4_PKE will cause the X86_FEATURE_OSPKE cpuid
bit to appear set. At this point in boot, identify_cpu()
has already run the actual CPUID instructions and populated
the "cpu features" structures. We need to go back and
re-run identify_cpu() to make sure it gets updated values.
We *could* simply re-populate the 11th word of the cpuid
data, but this is probably quick enough.
Also note that with the cpu_has() check and X86_FEATURE_PKU
present in disabled-features.h, we do not need an #ifdef

This relaxes the kernel Image placement requirements, so that it
may be placed at any 2 MB aligned offset in physical memory.
This is accomplished by ignoring PHYS_OFFSET when installing
memblocks, and accounting for the apparent virtual offset of
the kernel Image. As a result, virtual address references
below PAGE_OFFSET are correctly mapped onto physical references
into the kernel Image regardless of where it sits in memory.
Special care needs to be taken for dealing with memory limits passed
via mem=, since the generic implementation clips memory top down, which
may clip the kernel image itself if it is loaded high up in memory. To
deal with this case, we simply add back the memory covering the kernel
image, which may result in more memory to be retained than was passed
as a mem= parameter.
Since mem= should not be considered a production feature, a panic notifier
handler is installed that dumps the memory limit at panic time if one was
set.

mmapped netlink has a number of unresolved issues:
- TX zerocopy support had to be disabled more than a year ago via
commit 4682a03586 ("netlink: Always copy on mmap TX.")
because the content of the mmapped area can change after netlink
attribute validation but before message processing.
- RX support was implemented mainly to speed up nfqueue dumping packet
payload to userspace. However, since commit ae08ce0021
("netfilter: nfnetlink_queue: zero copy support") we avoid one copy
with the socket-based interface too (via the skb_zerocopy helper).
The other problem is that skbs attached to mmaped netlink socket
behave different from normal skbs:
- they don't have a shinfo area, so all functions that use skb_shinfo()
(e.g. skb_clone) cannot be used.
- reserving headroom prevents userspace from seeing the content as
it expects message to start at skb->head.
See for instance
commit aa3a022094 ("netlink: not trim skb for mmaped socket when dump").
- skbs handed e.g. to netlink_ack must have non-NULL skb->sk, else we
crash because it needs the sk to check if a tx ring is attached.
Also not obvious, leads to non-intuitive bug fixes such as 7c7bdf359
("netfilter: nfnetlink: use original skbuff when acking batches").
mmaped netlink also didn't play nicely with the skb_zerocopy helper
used by nfqueue and openvswitch. Daniel Borkmann fixed this via
commit 6bb0fef489 ("netlink, mmap: fix edge-case leakages in nf queue
zero-copy")' but at the cost of also needing to provide remaining
length to the allocation function.
nfqueue also has problems when used with mmaped rx netlink:
- mmaped netlink doesn't allow use of nfqueue batch verdict messages.
Problem is that in the mmap case, the allocation time also determines
the ordering in which the frame will be seen by userspace (A
allocating before B means that A is located in earlier ring slot,
but this also means that B might get a lower sequence number then A
since seqno is decided later. To fix this we would need to extend the
spinlocked region to also cover the allocation and message setup which
isn't desirable.
- nfqueue can now be configured to queue large (GSO) skbs to userspace.
Queing GSO packets is faster than having to force a software segmentation
in the kernel, so this is a desirable option. However, with a mmap based
ring one has to use 64kb per ring slot element, else mmap has to fall back
to the socket path (NL_MMAP_STATUS_COPY) for all large packets.
To use the mmap interface, userspace not only has to probe for mmap netlink
support, it also has to implement a recv/socket receive path in order to
handle messages that exceed the size of an rx ring element.

Huge amounts of help from Andy Lutomirski and Borislav Petkov to
produce this. Andy provided the inspiration to add classes to the
exception table with a clever bit-squeezing trick, Boris pointed
out how much cleaner it would all be if we just had a new field.
Linus Torvalds blessed the expansion with:
' I'd rather not be clever in order to save just a tiny amount of space
in the exception table, which isn't really criticial for anybody. '
The third field is another relative function pointer, this one to a
handler that executes the actions.
We start out with three handlers:
1: Legacy - just jumps the to fixup IP
2: Fault - provide the trap number in %ax to the fixup code
3: Cleaned up legacy for the uaccess error hack

Allow implementations of the match() callback in struct bus_type to
return errors and if it's -EPROBE_DEFER then queue the device for
deferred probing.
This is useful to buses such as AMBA in which devices are registered
before their matching information can be retrieved from the HW
(typically because a clock driver hasn't probed yet).

This adds real and virtual mode handlers for the H_PUT_TCE_INDIRECT and
H_STUFF_TCE hypercalls for user space emulated devices such as IBMVIO
devices or emulated PCI. These calls allow adding multiple entries
(up to 512) into the TCE table in one call which saves time on
transition between kernel and user space.
The current implementation of kvmppc_h_stuff_tce() allows it to be
executed in both real and virtual modes so there is one helper.
The kvmppc_rm_h_put_tce_indirect() needs to translate the guest address
to the host address and since the translation is different, there are
2 helpers - one for each mode.
This implements the KVM_CAP_PPC_MULTITCE capability. When present,
the kernel will try handling H_PUT_TCE_INDIRECT and H_STUFF_TCE if these
are enabled by the userspace via KVM_CAP_PPC_ENABLE_HCALL.
If they can not be handled by the kernel, they are passed on to
the user space. The user space still has to have an implementation
for these.
Both HV and PR-syle KVM are supported.

The arm,gic-v3 binding was written with good intentions and doesn't
enforce interrupt-cells to be 3, therefore making it easy to extend
the irq description in future if necessary:
> Cells 4 and beyond are reserved for future use.
Unfortunately, this sentence is immediately followed up with:
> When the 1st cell has a value of 0 or 1, cells 4 and beyond act as
> padding, and may be ignored. It is recommended that padding cells
> have a value of 0.
Consequently, any extensions to the PPI or SPI interrupt specifiers must
be able to work with random crap from legacy DTs, effectively
necessitating a new interrupt type in the first cell. Sigh.
This patch fixes the text so that additional, reserved cells are
required to be zero. This looks like a reasonable thing to require and
is already satisifed by the .dts files in-tree.

This driver allows an I2C bus to switch between multiple masters. This
is not hot-switching because connected I2C slaves will be
re-instantiated. It is meant to select the best I2C core at runtime once
the task is known. Example: Prefer i2c-gpio over another I2C core
because of HW errata affecting your use case.

In this rc, we've got more volume than previous rc, unsurprisingly;
the majority of updates in ASoC are about Intel drivers, and another
major changes are the continued plumbing of ALSA timer bugs revealed
by syzkaller fuzzer. Hopefully both settle down now.
Other than that, HD-audio received a couple of code fixes as well as

The userspace might need some sort of cache coherency management e.g. when CPU
and GPU domains are being accessed through dma-buf at the same time. To
circumvent this problem there are begin/end coherency markers, that forward
directly to existing dma-buf device drivers vfunc hooks. Userspace can make use
of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence would be
used like following:
- mmap dma-buf fd
- for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write
to mmap area 3. SYNC_END ioctl. This can be repeated as often as you
want (with the new data being consumed by the GPU or say scanout device)
- munmap once you don't need the buffer any more

Current "recovery" mount option will only try to use backup root.
However the word "recovery" is too generic and may be confusing for some
users.
Here introduce a new and more specific mount option, "usebackuproot" to
replace "recovery" mount option.
"Recovery" will be kept for compatibility reason, but will be
deprecated.
Also, since "usebackuproot" will only affect mount behavior and after
open_ctree() it has nothing to do with the filesystem, so clear the flag
after mount succeeded.
This provides the basis for later unified "norecovery" mount option.

This patch adds the DMA_ATTR_ALLOC_SINGLE_PAGES attribute to the
DMA-mapping subsystem.
This attribute can be used as a hint to the DMA-mapping subsystem that
it's likely not worth it to try to allocate large pages behind the
scenes. Large pages are likely to make an IOMMU TLB work more
efficiently but may not be worth it. See the Documentation contained in
this patch for more details about this attribute and when to use it.
Note that the name of the hint (DMA_ATTR_ALLOC_SINGLE_PAGES) is loosely
based on the name MADV_NOHUGEPAGE. Just as there is MADV_NOHUGEPAGE
vs. MADV_HUGEPAGE we could also add an "opposite" attribute to
DMA_ATTR_ALLOC_SINGLE_PAGES. Without having the "opposite" attribute
the lack of DMA_ATTR_ALLOC_SINGLE_PAGES means "use your best judgement
about whether to use small pages or large pages".

Each fw_cfg entry of type "file" has an associated 56-char,
nul-terminated ASCII string which represents its name. While
the fw_cfg device doesn't itself impose any specific naming
convention, QEMU developers have traditionally used path name
semantics (i.e. "etc/acpi/rsdp") to descriptively name the
various fw_cfg "blobs" passed into the guest.
This patch attempts, on a best effort basis, to create a
directory hierarchy representing the content of fw_cfg file
names, under /sys/firmware/qemu_fw_cfg/by_name.
Upon successful creation of all directories representing the
"dirname" portion of a fw_cfg file, a symlink will be created
to represent the "basename", pointing at the appropriate
/sys/firmware/qemu_fw_cfg/by_key entry. If a file name is not
suitable for this procedure (e.g., if its basename or dirname
components collide with an already existing dirname component
or basename, respectively) the corresponding fw_cfg blob is
skipped and will remain available in sysfs only by its selector
key value.

without explicit target CPU. The guarantee is gone now which can
break some usages in subtle ways. To flush out those cases, this
patch implements a debug feature which forces round-robin CPU

The debug feature defaults to off and can be enabled with a kernel
parameter. The default can be flipped with a debug config option.

schedstats is very useful during debugging and performance tuning but it
incurs overhead to calculate the stats. As such, even though it can be
disabled at build time, it is often enabled as the information is useful.
This patch adds a kernel command-line and sysctl tunable to enable or
disable schedstats on demand (when it's built in). It is disabled
by default as someone who knows they need it can also learn to enable
it when necessary.
The benefits are dependent on how scheduler-intensive the workload is.
If it is then the patch reduces the number of cycles spent calculating
the stats with a small benefit from reducing the cache footprint of the
scheduler.
These measurements were taken from a 48-core 2-socket
machine with Xeon(R) E5-2670 v3 cpus although they were also tested on a
single socket machine 8-core machine with Intel i7-3770 processors.

Small improvement and similar gains were seen on the UMA machine.
The gain is small but it stands to reason that doing less work in the
scheduler is a good thing. The downside is that the lack of schedstats and
tracepoints may be surprising to experts doing performance analysis until
they find the existence of the schedstats= parameter or schedstats sysctl.
It will be automatically activated for latencytop and sleep profiling to
alleviate the problem. For tracepoints, there is a simple warning as it's
not safe to activate schedstats in the context when it's known the tracepoint
may be wanted but is unavailable.

Centralize gmux' ACPI HID in a header file and add apple_gmux_present().
This can be used by other drivers to activate quirks specific to dual
GPU MacBook Pros & Mac Pros. The alternative would be to hardcode DMI

Allow handlers to declare their capabilities and allow clients to
obtain that information. So far we have these use cases:
* If the handler is able to switch DDC separately, clients need to
probe EDID with drm_get_edid_switcheroo(). We should allow them
to detect a capable handler to ensure this function only gets
called when needed.
* Likewise if the handler is unable to switch AUX separately, the active
client needs to communicate link training parameters to the inactive
client, which may then skip the AUX handshake and set up its output
with these pre-calibrated values (DisplayPort specification v1.1a,
section 2.5.3.3). Clients need a way to recognize such a situation.
The flags for the radeon_atpx_handler and amdgpu_atpx_handler are
initially set to 0, this can later on be amended with
handler_flags |= VGA_SWITCHEROO_CAN_SWITCH_DDC;
when a ->switch_ddc callback is added.

LS-WVL/VL are both kirkwood-6282 based NAS devices, which share
many MPP pins. However they are slightly different:
- LS-WVL is 2-Bay NAS, and LS-VL is only 1-Bay.
- There're two red LED indicator on LS-WVL to show when HDD fails,
which is similar to LS-WXL, but there's no such on LS-VL.
So after the split, common part goes into .dtsi file:
- kirkwood-linkstation-6282.dtsi
while all rest part goes into device specific .dts file:
- kirkwood-linkstation-lsvl.dts
- kirkwood-linkstation-lswvl.dts

Since the commit a526973e02 ("pinctrl: mvebu: Fix mapping of pin
63 (gpo -> gpio)"), the mpp63 is no more declared as a GPO but is a
GPIO. Even if in the datasheet this pin is described as GPO, the
experience of the D-Link DNS-327L board shows that it can be used as a
GPIO.
This commits generated warnings for the board using this pin as gpo, with
this patch the dts are fixed by using the new function (gpio) instead of
the old one.
The binding documentation has also been updated accordingly.

This patch removes range-based information used for optimizations in
begin_cpu_access and end_cpu_access.
We don't have any user nor implementation using range-based flush. It seems a
consensus that if we ever want something like that again (or even more robust
using 2D, 3D sub-range regions) we can use the upcoming dma-buf sync ioctl for
such.
