 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.

d56154c7e8 pwm: Changes for v5.11-rc1 
This is a fairly big release cycle from the PWM framework's point of
 view. There's a large patcheset here which converts drivers to use the
 new devm_platform_ioremap_resource() helper and a bunch of minor fixes
 to existing drivers. Some of the existing drivers also add support for
 more hardware, such as Atmel SAMA 5D2 and Mediatek MT8183.
 
 Finally there's a couple of new drivers for Intel Keem Bay and LGM SoCs
 as well as the DesignWare PWM controller.

320d159e2d dt-bindings: rtc: add reset-source property 
Some RTCs, e.g. the pcf2127, can be used as a hardware watchdog. But
if the reset pin is not actually wired up, the driver exposes a
watchdog device that doesn't actually work.

Provide a standard binding that can be used to indicate that a given
RTC can perform a reset of the machine, similar to wakeup-source.

d69c6ddd01 dt-bindings: Fix JSON pointers 
The correct syntax for JSON pointers begins with a '/' after the '#'.
Without a '/', the string should be interpreted as a subschema
identifier. The jsonschema module currently doesn't handle subschema
identifiers and incorrectly allows JSON pointers to begin without a '/'.
Let's fix this before it becomes a problem when jsonschema module is
fixed.

e2ae634014 RISC-V Patches for the 5.11 Merge Window, Part 1 
We have a handful of new kernel features for 5.11:
 
 * Support for the contiguous memory allocator.
 * Support for IRQ Time Accounting
 * Support for stack tracing
 * Support for strict /dev/mem
 * Support for kernel section protection
 
 I'm being a bit conservative on the cutoff for this round due to the
 timing, so this is all the new development I'm going to take for this
 cycle (even if some of it probably normally would have been OK).  There
 are, however, some fixes on the list that I will likely be sending along
 either later this week or early next week.
 
 There is one issue in here: one of my test configurations
 (PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of the
 .text.init alignment patch.  With any luck we'll sort out the issue, but
 given how many bugs get fixed all over the place and how unrelated those
 features seem my guess is that we're just running into something that's
 been lurking for a while and has already been fixed in the newer QEMU
 (though I wouldn't be surprised if it's one of these implicit
 assumptions we have in the boot flow).  If it was hardware I'd be
 strongly inclined to look more closely, but given that users can upgrade
 their simulators I'm less worried about it.
 
 There are two merge conflicts, both in build files.  They're both a bit
 clunky: arch/riscv/Kconfig is out of order (I have a script that's
 supposed to keep them in order, I'll fix it) and lib/Makefile is out of
 order (though GENERIC_LIB here doesn't mean quite what it does above).

  With any luck we'll sort out the issue, but given how many bugs get
  fixed all over the place and how unrelated those features seem my
  guess is that we're just running into something that's been lurking
  for a while and has already been fixed in the newer QEMU (though I
  wouldn't be surprised if it's one of these implicit assumptions we
  have in the boot flow). If it was hardware I'd be strongly inclined to
  look more closely, but given that users can upgrade their simulators
  I'm less worried about it"

a409ed156a This is the bulk of the GPIO changes for the v5.11 kernel cycle: 
Core changes:
 
 - Retired the old set-up function for GPIO IRQ chips. All chips
   now use the template struct gpio_irq_chip and pass that to the core
   to be set up alongside the gpio_chip. We can finally get rid of
   the old cruft.
 
 - Some refactoring and clean up of the core code.
 
 - Support edge event timestamps to be stamped using REALTIME
   (wall clock) timestamps. We have found solid use cases for
   this, so we support it.
 
 New drivers:
 
 - MStar MSC313 GPIO driver.
 
 - HiSilicon GPIO driver.
 
 Driver improvements:
 
 - The PCA953x driver now also supports the NXP PCAL9554B/C chips.
 
 - The mockup driver can now be probed from the device tree which
   is pretty useful for virtual prototyping of devices.
 
 - The Rcar driver now supports .get_multiple()
 
 - The MXC driver dropped some legacy and became a pure device
   tree client.
 
 - The Exar driver was moved over to the IDA interface for
   enumerating, and also switched over to using regmap for
   register access.

09c0796adf Tracing updates for 5.11 
The major update to this release is that there's a new arch config option called:
 CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it.
 All the ftrace callbacks now take a struct ftrace_regs instead of a struct
 pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then
 the ftrace_regs will have enough information to read the arguments of the
 function being traced, as well as access to the stack pointer. This way, if
 a user (like live kernel patching) only cares about the arguments, then it
 can avoid using the heavier weight "regs" callback, that puts in enough
 information in the struct ftrace_regs to simulate a breakpoint exception
 (needed for kprobes).
 
 New config option that audits the timestamps of the ftrace ring buffer at
 most every event recorded.  The "check_buffer()" calls will conflict with
 mainline, because I purposely added the check without including the fix that
 it caught, which is in mainline. Running a kernel built from the commit of
 the added check will trigger it.
 
 Ftrace recursion protection has been cleaned up to move the protection to
 the callback itself (this saves on an extra function call for those
 callbacks).
 
 Perf now handles its own RCU protection and does not depend on ftrace to do
 it for it (saving on that extra function call).
 
 New debug option to add "recursed_functions" file to tracefs that lists all
 the places that triggered the recursion protection of the function tracer.
 This will show where things need to be fixed as recursion slows down the
 function tracer.
 
 The eval enum mapping updates done at boot up are now offloaded to a work
 queue, as it caused a noticeable pause on slow embedded boards.
 
 Various clean ups and last minute fixes.

Pull overlayfs updates from Miklos Szeredi:

 - Allow unprivileged mounting in a user namespace.

   For quite some time the security model of overlayfs has been that
   operations on underlying layers shall be performed with the
   privileges of the mounting task.

   This way an unprvileged user cannot gain privileges by the act of
   mounting an overlayfs instance. A full audit of all function calls
   made by the overlayfs code has been performed to see whether they
   conform to this model, and this branch contains some fixes in this
   regard.

 - Support running on copied filesystem images by optionally disabling
   UUID verification.

 - Bug fixes as well as documentation updates.

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.

48c1c40ab4 ARM: SoC drivers for v5.11 
There are a couple of subsystems maintained by other people that
 merge their drivers through the SoC tree, those changes include:
 
  - The SCMI firmware framework gains support for sensor notifications
    and for controlling voltage domains.
 
  - A large update for the Tegra memory controller driver, integrating
    it better with the interconnect framework
 
  - The memory controller subsystem gains support for Mediatek MT8192
 
  - The reset controller framework gains support for sharing pulsed
    resets
 
 For Soc specific drivers in drivers/soc, the main changes are
 
  - The Allwinner/sunxi MBUS gets a rework for the way it handles
    dma_map_ops and offsets between physical and dma address spaces.
 
  - An errata fix plus some cleanups for Freescale Layerscape SoCs
 
  - A cleanup for renesas drivers regarding MMIO accesses.
 
  - New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
 
  - New SoC specific drivers for Aspeed AST2600 LPC bus control
    and SoC identification.
 
  - Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
    and SDX55.
 
  - A rework of the TI AM33xx 'genpd' power domain support to use
    information from DT instead of platform data
 
  - Support for TI AM64x SoCs
 
  - Allow building some Amlogic drivers as modules instead of built-in
 
 Finally, there are numerous cleanups and smaller bug fixes for
 Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
 Renesas, and Xilinx SoCs.
 
 There is a trivial conflict in the cedrus driver, with two branches
 adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
 remove/remove conflict in linux/dma-mapping.h.

9805529ec5 ARM: device tree updates for 5.11 
Across all platforms, there is a continued move towards DT schema for
 validating the dts files. As a result there are bug fixes for mistakes
 that are found using these schema, in addition to warnings from the
 dtc compiler.
 
 As usual, many changes are for adding support for additional on-chip
 and on-board components in the machines we already support.
 
 The newly supported SoCs for this release are:
 
  - MStar Infinity2M, a low-end IP camera chip based on a dual-core
    Cortex-A7, otherwise similar to the Infinity chip we already support.
    This is also known as the SigmaStar SSD202D, and we add support for
    the Honestar ssd201htv2 development kit.
 
  - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
    (BMC), in the same family as the NPCM750. This gets used in the Ampere
    Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
    added as well.
 
  - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
    Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
    GT-AC5300 high-end WiFi router based on this chip.
 
  - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,

Pull ARM device tree updates from Arnd Bergmann:
 "Across all platforms, there is a continued move towards DT schema for
  validating the dts files. As a result there are bug fixes for mistakes
  that are found using these schema, in addition to warnings from the
  dtc compiler.

  As usual, many changes are for adding support for additional on-chip
  and on-board components in the machines we already support.

  The newly supported SoCs for this release are:

   - MStar Infinity2M, a low-end IP camera chip based on a dual-core
     Cortex-A7, otherwise similar to the Infinity chip we already
     support. This is also known as the SigmaStar SSD202D, and we add
     support for the Honestar ssd201htv2 development kit.

   - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
     (BMC), in the same family as the NPCM750. This gets used in the
     Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of
     which are added as well.

   - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
     Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
     GT-AC5300 high-end WiFi router based on this chip.

   - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
     meant for faster Chromebooks and tablets. It gets added along with
     its reference design.

   - Mediatek MT6779 (Helio P90) is a high-end phone chip from last
     year's generation, also added along with its reference board. This
     one is still based on Cortex-A75/A55.

Merge tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v5.11 kernel.

  Drivers, drivers and drivers. Not a single core change.

  Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
  SoCs.

  As part of the modularization attempt, I applied one patch affecting
  the firmware subsystem as a functional (not syntactic/semantic)
  dependency and then it blew up in our face, so I had to revert it,
  bummer. It will come in later, through that subsystem, I guess.

  New drivers:

   - New driver for the Microchip Serial GPIO "SGPIO".

   - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

  New subdrivers:

   - Intel Lakefield subdriver.

   - Intel Elkhart Lake subdriver.

   - Intel Alder Lake-S subdriver.

   - Qualcomm MSM8953 subdriver.

   - Qualcomm SDX55 subdriver.

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.

  Summary:

   - IOVA allocation optimisations and removal of unused code

   - Introduction of DOMAIN_ATTR_IO_PGTABLE_CFG for parameterising the
     page-table of an IOMMU domain

   - Support for changing the default domain type in sysfs

   - Optimisation to the way in which identity-mapped regions are
     created

   - Driver updates:
       * Arm SMMU updates, including continued work on Shared Virtual
         Memory

7a932e5702 asm-generic: cross-architecture timer cleanup 
This cleans up two ancient timer features that were never completed in
 the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
 
 There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
 of clocksource implementations, the ARM EBSA110 platform. Rather than
 changing to use modern timekeeping, we remove the platform entirely as
 Russell no longer uses his machine and nobody else seems to have one
 any more.
 
 The conditional code for using arch_gettimeoffset() is removed as
 a result.
 
 For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
 not using clockevent drivers: parisc, ia64, most of m68k, and one
 Arm platform. These all do timer ticks slighly differently, and this
 gets cleaned up to the point they at least all call the same helper
 function. Instead of most platforms using 'select GENERIC_CLOCKEVENTS'
 in Kconfig, the polarity is now reversed, with the few remaining ones
 selecting LEGACY_TIMER_TICK instead.

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.

c637693b20 ubsan: remove UBSAN_MISC in favor of individual options 
Make each UBSAN option individually selectable and remove UBSAN_MISC which
no longer has any purpose.  Add help text for each Kconfig, and include a
reference to the Clang sanitizer documentation.  Disable unsigned overflow
by default (not available with GCC and makes x86 unbootable with Clang).
Disable unreachable when objtool is in use (redundant and confuses things:
instrumentation appears at unreachable locations).

ca4a9241cc kdump: append uts_namespace.name offset to VMCOREINFO 
The offset of the field 'init_uts_ns.name' has changed since commit
9a56493f69 ("uts: Use generic ns_common::count").

Make the offset of the field 'uts_namespace.name' available in VMCOREINFO
because tools like 'crash-utility' and 'makedumpfile' must be able to read
it from crash dumps.

fe71988834 proc: provide details on indirect branch speculation 
Similar to speculation store bypass, show information about the indirect
branch speculation mode of a task in /proc/$pid/status.

For testing/benchmarking, I needed to see whether IB (Indirect Branch)
speculation (see Spectre-v2) is enabled on a task, to see whether an
IBPB instruction should be executed on an address space switch.
Unfortunately, this information isn't available anywhere else and
currently the only way to get it is to hack the kernel to expose it
(like this change).  It also helped expose a bug with conditional IB
speculation on certain CPUs.

Another place this could be useful is to audit the system when using
sanboxing.  With this change, I can confirm that seccomp-enabled
process have IB speculation force disabled as expected when the kernel
command line parameter `spectre_v2_user=seccomp`.

Since there's already a 'Speculation_Store_Bypass' field, I used that
as precedent for adding this one.

faf145d6f3 Merge branch 'exec-for-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace 
Pull execve updates from Eric Biederman:
 "This set of changes ultimately fixes the interaction of posix file
  lock and exec. Fundamentally most of the change is just moving where
  unshare_files is called during exec, and tweaking the users of
  files_struct so that the count of files_struct is not unnecessarily
  played with.

  Along the way fcheck and related helpers were renamed to more
  accurately reflect what they do.

  There were also many other small changes that fell out, as this is the
  first time in a long time much of this code has been touched.

  Benchmarks haven't turned up any practical issues but Al Viro has
  observed a possibility for a lot of pounding on task_lock. So I have
  some changes in progress to convert put_files_struct to always rcu
  free files_struct. That wasn't ready for the merge window so that will
  have to wait until next time"

Merge tag 'nfsd-5.11' of git://git.linux-nfs.org/projects/cel/cel-2.6

Pull nfsd updates from Chuck Lever:
 "Several substantial changes this time around:

   - Previously, exporting an NFS mount via NFSD was considered to be an
     unsupported feature. With v5.11, the community has attempted to
     make re-exporting a first-class feature of NFSD.

     This would enable the Linux in-kernel NFS server to be used as an
     intermediate cache for a remotely-located primary NFS server, for
     example, even with other NFS server implementations, like a NetApp
     filer, as the primary.

   - A short series of patches brings support for multiple RPC/RDMA data
     chunks per RPC transaction to the Linux NFS server's RPC/RDMA
     transport implementation.

     This is a part of the RPC/RDMA spec that the other premiere
     NFS/RDMA implementation (Solaris) has had for a very long time, and
     completes the implementation of RPC/RDMA version 1 in the Linux
     kernel's NFS server.

   - Long ago, NFSv4 support was introduced to NFSD using a series of C
     macros that hid dprintk's and goto's. Over time, the kernel's XDR
     implementation has been greatly improved, but these C macros have
     remained and become fallow. A series of patches in this pull
     request completely replaces those macros with the use of current
     kernel XDR infrastructure. Benefits include:

       - More robust input sanitization in NFSD's NFSv4 XDR decoders.

       - Make it easier to use common kernel library functions that use
         XDR stream APIs (for example, GSS-API).

       - Align the structure of the source code with the RFCs so it is
         easier to learn, verify, and maintain our XDR implementation.

       - Removal of more than a hundred hidden dprintk() call sites.

       - Removal of some explicit manipulation of pages to help make the
         eventual transition to xdr->bvec smoother.

   - On top of several related fixes in 5.10-rc, there are a few more
     fixes to get the Linux NFSD implementation of NFSv4.2 inter-server
     copy up to speed.

  And as usual, there is a pinch of seasoning in the form of a
  collection of unrelated minor bug fixes and clean-ups.

  Many thanks to all who contributed this time around!"

ef9df00117 remoteproc updates for v5.11 
This introduces support for controlling the TI PRU, adds hooks for
 remoteproc drivers to override the default ELF based coredump format,
 introduces a library function for coredumps using named sections (aka
 the Qualcomm "minidump" format). It fixes a problem with inconsistent
 notifications sent by the Qualcomm sysmon driver to the remote
 processors and it migrates the Qualcomm MSS driver to use power-domains
 for resources that aren't actually regulators.  Lastly it contains a
 number of fixes for minor bugs and build warnings throughout the
 drivers.

605ea5aafe spi: Updates for v5.11 
The big change this release has been some excellent work from Lukas
 Wunner which closes a bunch of holes in the cleanup paths for drivers,
 mainly introduced as a result of devm conversions causing bad
 interactions with the support SPI has for allocating the bus and driver
 data together.  Together with some of the other work done it feels like
 we've turned the corner on several long standing pain points with the
 API.
 
  - Many cleanups around probe/remove and error handling from Lukas
    Wunner and Uwe Kleine-König, and further fixes around PM from Zhang
    Qilong.
  - Provide a mask for which bits of the mode can safely be configured by
    drivers and use that to fix an issue with the ADS7846 driver.
  - Documentation of the expected interactions between SPI and GPIO level
    chip select polarity configuration from H. Nikolaus Schaller,
    hopefully we're pretty much at the end of sorting out the
    interactions there.  Thanks to Nikolaus, Sven Van Asbroeck and Linus
    Walleij for this.
  - DMA support for Allwinner sun6i controllers.
  - Support for Canaan K210 Designware implementations and Intel Adler Lake.

2dda5700ef regulator: Updates for v5.11 
This has been a quiet release for the regulator API, a few new drivers
 and the usual fixes and cleanup traffic but not much else going on:
 
  - Optimisations for the handling of voltage enumeration, especially
    with sparse selector sets, from Claudiu Beznea.
  - Support for several ARM SCMI regulators, Dialog DA9121, NXP PF8x00,
    Qualcomm PMX55, PM8350 and PM8350c
 
 The addition of the SCMI regulator driver (which controls regulators via
 system firmware) means that we've pulled in the support for the underlying
 firmware operations from the firmware tree.

15b4473617 mm/lru: revise the comments of lru_lock 
Since we changed the pgdat->lru_lock to lruvec->lru_lock, it's time to fix
the incorrect comments in code.  Also fixed some zone->lru_lock comment
error from ancient time.  etc.

I struggled to understand the comment above move_pages_to_lru() (surely
it never calls page_referenced()), and eventually realized that most of
it had got separated from shrink_active_list(): move that comment back.

c367caf1a3 sound updates for 5.11-rc1 
Lots of changes (slightly more code increase than usual) at this
 time, while most of code changes are ASoC driver-specific.
 Here goes some highlight:
 
 Core:
 * The new auxiliary bus implementation for Intel DSP, which will
   be used by other drivers as well
 * Lots of ASoC core cleanups and refactoring
 * UBSAN and KCSAN fixes in rawmidi, sequencer and a few others
 * Compress-offload API enhancement for the pause during draining
 
 HD- and USB-audio:
 * Enhancements of the USB-audio implicit feedback support,
   including better full-duplex operations
 * Continued CA0132 improvements and fixes
 * A few new quirk entries, HDMI audio fixes
 
 ASoC:
 * Support for boot time selection of Intel DSP firmware, which
   should help distros/users testing new stuff more easily;
   the kconfig was moved to boot time option, too
 * Some basic DPCM support in audio graph card
 * Removal of old pre-DT Freescale drivers
 * Support for Allwinner H6 I2S, Analog Devices ADAU1372, Intel
   Alderlake-S, GMediatek MT8192, NXP i.MX HDMI and XCVR, Realtek
   RT715, Qualcomm SM8250 and simple GPIO based muxes

194e28da1a zram: add stat to gather incompressible pages since zram set up 
Currently, zram supports the stat via /sys/block/zram/mm_stat to represent
how many of incompressible pages are stored at the moment but it couldn't
show how many times incompressible pages were wrote down since zram set
up.  It's also good indication to see how zram is effective in the system.

0d8359620d zram: support page writeback 
There is demand to writeback specific process pages to backing store
instead of all idles pages in the system due to storage wear out concerns
and to launching latency of apps which are most of the time idle but are
critical for resume latency.

This patch extends the writeback knob to support a specific page
writeback.

d0d4730ac2 userfaultfd: add user-mode only option to unprivileged_userfaultfd sysctl knob 
With this change, when the knob is set to 0, it allows unprivileged users
to call userfaultfd, like when it is set to 1, but with the restriction
that page faults from only user-mode can be handled.  In this mode, an
unprivileged user (without SYS_CAP_PTRACE capability) must pass
UFFD_USER_MODE_ONLY to userfaultd or the API will fail with EPERM.

This enables administrators to reduce the likelihood that an attacker with
access to userfaultfd can delay faulting kernel code to widen timing
windows for other exploits.

The default value of this knob is changed to 0.  This is required for
correct functioning of pipe mutex.  However, this will fail postcopy live
migration, which will be unnoticeable to the VM guests.  To avoid this,
set 'vm.userfault = 1' in /sys/sysctl.conf.

The main reason this change is desirable as in the short term is that the
Android userland will behave as with the sysctl set to zero.  So without
this commit, any Linux binary using userfaultfd to manage its memory would
behave differently if run within the Android userland.  For more details,
refer to Andrea's reply [1].

5e545df329 arm: remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL 
ARM is the only architecture that defines CONFIG_ARCH_HAS_HOLES_MEMORYMODEL
which in turn enables memmap_valid_within() function that is intended to
verify existence  of struct page associated with a pfn when there are holes
in the memory map.

However, the ARCH_HAS_HOLES_MEMORYMODEL also enables HAVE_ARCH_PFN_VALID
and arch-specific pfn_valid() implementation that also deals with the holes
in the memory map.

The only two users of memmap_valid_within() call this function after
a call to pfn_valid() so the memmap_valid_within() check becomes redundant.

Remove CONFIG_ARCH_HAS_HOLES_MEMORYMODEL and memmap_valid_within() and rely
entirely on ARM's implementation of pfn_valid() that is now enabled
unconditionally.

f0c0c115fb mm: memcontrol: account pagetables per node 
For many workloads, pagetable consumption is significant and it makes
sense to expose it in the memory.stat for the memory cgroups.  However at
the moment, the pagetables are accounted per-zone.  Converting them to
per-node and using the right interface will correctly account for the
memory cgroups as well.

b8eddff888 mm: memcontrol: add file_thp, shmem_thp to memory.stat 
As huge page usage in the page cache and for shmem files proliferates in
our production environment, the performance monitoring team has asked for
per-cgroup stats on those pages.

We already track and export anon_thp per cgroup.  We already track file
THP and shmem THP per node, so making them per-cgroup is only a matter of
switching from node to lruvec counters.  All callsites are in places where
the pages are charged and locked, so page->memcg is stable.

a9bed1e1c2 selftests/vm: only some gup_test items are really benchmarks 
Therefore, some minor cleanup and improvements are in order:

1. Rename the other items appropriately.

2. Stop reporting timing information on the non-benchmark items. It's
   still being recorded and is available, but there's no point in
   cluttering up the report with data that no one reasonably needs to
   check.

3. Don't do iterations, for non-benchmark items.

4. Print out a shorter, more appropriate report for the non-benchmark
   tests.

5. Add the command that was run, to the report. This really helps, as
   there are quite a lot of options now.

6. Use a larger integer type for cmd, now that it's being compared
   Otherwise it doesn't work, because in this case cmd is about 3 billion,
   which is the perfect size for problems with signed vs unsigned int.

9c84f22926 mm/gup_benchmark: rename to mm/gup_test 
Patch series "selftests/vm: gup_test, hmm-tests, assorted improvements", v3.

Summary: This series provides two main things, and a number of smaller
supporting goodies.  The two main points are:

1) Add a new sub-test to gup_test, which in turn is a renamed version
   of gup_benchmark.  This sub-test allows nicer testing of dump_pages(),
   at least on user-space pages.

   For quite a while, I was doing a quick hack to gup_test.c whenever I
   wanted to try out changes to dump_page().  Then Matthew Wilcox asked me
   what I meant when I said "I used my dump_page() unit test", and I
   realized that it might be nice to check in a polished up version of
   that.

   Details about how it works and how to use it are in the commit
   description for patch #6 ("selftests/vm: gup_test: introduce the
   dump_pages() sub-test").

2) Fixes a limitation of hmm-tests: these tests are incredibly useful,
   but only if people actually build and run them.  And it turns out that
   libhugetlbfs is a little too effective at throwing a wrench in the
   works, there.  So I've added a little configuration check that removes
   just two of the 21 hmm-tests, if libhugetlbfs is not available.

   Further details in the commit description of patch #8
   ("selftests/vm: hmm-tests: remove the libhugetlbfs dependency").

Other smaller things that this series does:

a) Remove code duplication by creating gup_test.h.

b) Clear up the sub-test organization, and their invocation within
   run_vmtests.sh.

c) Other minor assorted improvements.

[1] v2 is here:
https://lore.kernel.org/linux-doc/20200929212747.251804-1-jhubbard@nvidia.com/

[2] https://lore.kernel.org/r/CAHk-=wgh-TMPHLY3jueHX7Y2fWh3D+nMBqVS__AZm6-oorquWA@mail.gmail.com

This patch (of 9):

Rename nearly every "gup_benchmark" reference and file name to "gup_test".
The one exception is for the actual gup benchmark test itself.

The current code already does a *little* bit more than benchmarking, and
definitely covers more than get_user_pages_fast().  More importantly,
however, subsequent patches are about to add some functionality that is
non-benchmark related.

Closely related changes:

* Kconfig: in addition to renaming the options from GUP_BENCHMARK to
  GUP_TEST, update the help text to reflect that it's no longer a
  benchmark-only test.

9cc7e96aa8 mm/page_owner: record timestamp and pid 
Collect the time for each allocation recorded in page owner so that
allocation "surges" can be measured.

Record the pid for each allocation recorded in page owner so that the
source of allocation "surges" can be better identified.

The above is very useful when doing memory analysis.  On a crash for
example, we can get this information from kdump (or ramdump) and parse it
to figure out memory allocation problems.

Please note that on x86_64 this increases the size of struct page_owner
from 16 bytes to 32.

Vlastimil: it's not a functionality intended for production, so unless
somebody says they need to enable page_owner for debugging and this
increase prevents them from fitting into available memory, let's not
complicate things with making this optional.

edd7ab7684 The new preemtible kmap_local() implementation: 
- Consolidate all kmap_atomic() internals into a generic implementation
     which builds the base for the kmap_local() API and make the
     kmap_atomic() interface wrappers which handle the disabling/enabling of
     preemption and pagefaults.
 
   - Switch the storage from per-CPU to per task and provide scheduler
     support for clearing mapping when scheduling out and restoring them
     when scheduling back in.
 
   - Merge the migrate_disable/enable() code, which is also part of the
     scheduler pull request. This was required to make the kmap_local()
     interface available which does not disable preemption when a mapping
     is established. It has to disable migration instead to guarantee that
     the virtual address of the mapped slot is the same accross preemption.
 
   - Provide better debug facilities: guard pages and enforced utilization
     of the mapping mechanics on 64bit systems when the architecture allows
     it.
 
   - Provide the new kmap_local() API which can now be used to cleanup the
     kmap_atomic() usage sites all over the place. Most of the usage sites
     do not require the implicit disabling of preemption and pagefaults so
     the penalty on 64bit and 32bit non-highmem systems is removed and quite
     some of the code can be simplified. A wholesale conversion is not
     possible because some usage depends on the implicit side effects and
     some need to be cleaned up because they work around these side effects.
 
     The migrate disable side effect is only effective on highmem systems
     and when enforced debugging is enabled. On 64bit and 32bit non-highmem
     systems the overhead is completely avoided.

1ac0884d54 A set of updates for entry/exit handling: 
- More generalization of entry/exit functionality
 
  - The consolidation work to reclaim TIF flags on x86 and also for non-x86
    specific TIF flags which are solely relevant for syscall related work
    and have been moved into their own storage space. The x86 specific part
    had to be merged in to avoid a major conflict.
 
  - The TIF_NOTIFY_SIGNAL work which replaces the inefficient signal
    delivery mode of task work and results in an impressive performance
    improvement for io_uring. The non-x86 consolidation of this is going to
    come seperate via Jens.
 
  - The selective syscall redirection facility which provides a clean and
    efficient way to support the non-Linux syscalls of WINE by catching them
    at syscall entry and redirecting them to the user space emulation. This
    can be utilized for other purposes as well and has been designed
    carefully to avoid overhead for the regular fastpath. This includes the
    core changes and the x86 support code.
 
  - Simplification of the context tracking entry/exit handling for the users
    of the generic entry code which guarantee the proper ordering and
    protection.
 
  - Preparatory changes to make the generic entry code accomodate S390
    specific requirements which are mostly related to their syscall restart
    mechanism.

  - A mechanism from Mauro to automatically format Documentation/features

0ca2ce81eb arm64 updates for 5.11: 
- Expose tag address bits in siginfo. The original arm64 ABI did not
   expose any of the bits 63:56 of a tagged address in siginfo. In the
   presence of user ASAN or MTE, this information may be useful. The
   implementation is generic to other architectures supporting tags (like
   SPARC ADI, subject to wiring up the arch code). The user will have to
   opt in via sigaction(SA_EXPOSE_TAGBITS) so that the extra bits, if
   available, become visible in si_addr.
 
 - Default to 32-bit wide ZONE_DMA. Previously, ZONE_DMA was set to the
   lowest 1GB to cope with the Raspberry Pi 4 limitations, to the
   detriment of other platforms. With these changes, the kernel scans the
   Device Tree dma-ranges and the ACPI IORT information before deciding
   on a smaller ZONE_DMA.
 
 - Strengthen READ_ONCE() to acquire when CONFIG_LTO=y. When building
   with LTO, there is an increased risk of the compiler converting an
   address dependency headed by a READ_ONCE() invocation into a control
   dependency and consequently allowing for harmful reordering by the
   CPU.
 
 - Add CPPC FFH support using arm64 AMU counters.
 
 - set_fs() removal on arm64. This renders the User Access Override (UAO)
   ARMv8 feature unnecessary.
 
 - Perf updates: PMU driver for the ARM DMC-620 memory controller, sysfs
   identifier file for SMMUv3, stop event counters support for i.MX8MP,
   enable the perf events-based hard lockup detector.
 
 - Reorganise the kernel VA space slightly so that 52-bit VA
   configurations can use more virtual address space.
 
 - Improve the robustness of the arm64 memory offline event notifier.
 
 - Pad the Image header to 64K following the EFI header definition
   updated recently to increase the section alignment to 64K.
 
 - Support CONFIG_CMDLINE_EXTEND on arm64.
 
 - Do not use tagged PC in the kernel (TCR_EL1.TBID1==1), freeing up 8
   bits for PtrAuth.
 
 - Switch to vmapped shadow call stacks.
 
 - Miscellaneous clean-ups.

4aa5b78fb5 dt-bindings: i2c: dw: cancel mandatory requirements for "#address-cells" and "#size-cells" 
The "#address-cells" and "#size-cells" are required only when the I2C
controller has subnodes. However, some I2C controllers defined in
"arch/arm64/boot/dts/amd/" and "arch/arm64/boot/dts/hisilicon/"
directories do not have child nodes. So they don't need these two
properties and don't write them explicitly.

Therefore, setting properties "#address-cells" and "#size-cells" as
"required" in this yaml file causes the following warnings:
/root/linux-next/arch/arm64/boot/dts/hisilicon/hi6220-hikey.dt.yaml: \
i2c@f7100000: '#address-cells' is a required property

2d2f2d7322 ovl: user xattr 
Optionally allow using "user.overlay." namespace instead of
"trusted.overlay."

This is necessary for overlayfs to be able to be mounted in an unprivileged
namepsace.

Make the option explicit, since it makes the filesystem format be
incompatible.

Disable redirect_dir and metacopy options, because these would allow
privilege escalation through direct manipulation of the
"user.overlay.redirect" or "user.overlay.metacopy" xattrs.

13458ffe0a net: x25: Remove unimplemented X.25-over-LLC code stubs 
According to the X.25 documentation, there was a plan to implement
X.25-over-802.2-LLC. It never finished but left various code stubs in the
X.25 code. At this time it is unlikely that it would ever finish so it
may be better to remove those code stubs.

Also change the documentation to make it clear that this is not a ongoing
plan anymore. Change words like "will" to "could", "would", etc.
