Pull spi updates from Mark Brown:
 "The big update this time around is some excellent work from David
  Jander who went through the fast path and really eliminated overheads,
  meaning that we are seeing a huge reduction in the time spent between
  transfers for single threaded clients.

  Benchmarking has been coming out at about a halving of overhead which
  is clearly visible in system level usage that stresses SPI like some
  CAN and IIO applications, especially with small transfers. Thanks to
  David for taking the time to drill down into this and push the work
  upstream.

  Otherwise there's been a bunch of new device support and the usual
  updates.

   - Optimisation of the fast path, particularly around the number and
     types of locking operations, from David Jander.

   - Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder
     Bay, MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241
     and Samsung Exynos Auto v9 and 4210"

Pull ARM boardfile deprecation from Arnd Bergmann:
 "Over the past ten years, new machine support was based on device tree,
  and an initial set of about 400 boards using ATAGS with boardfile for
  booting were grandfathered in, with about half of them either removed
  or converted to DT over time.

  Based on the recent mailing list discussion I started, I have now
  turned the findings into a set of patches that marks most board files
  as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.

  For the boards that are marked as unused, there are two final chances
  for potential users: The removal is scheduled to take place after the
  longterm stable kernel at the end of 2022, so users can stay on that
  version for another few years, and if anyone still has one of these
  machines and is planning to keep updating kernels beyond that version,
  they can speak up now to have their boards taken off the list again.

  Waiting for the LTS release also makes sure that there will be at
  least one longterm kernel that contains the recent multiplatform
  conversion along while still supporting all legacy boards.

  The short summary of the current status is:

   - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
     users and will be removed entirely.

   - The mmp and davinci platforms have DT support for the important
     machines and will become DT-only after this.

   - s3c64xx, dove, orion5x, and pxa keep some board files to allow
     those to be migrated over to DT more easily, but most board files
     are getting removed now. DT support on these platforms is partially
     working but requires changes to additional drivers for the other
     boards.

   - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
     moment but have some boards with known users. Removing the board
     files that nobody uses should make it easier to try a DT conversion
     if anyone cares.

  There is no explicit timeline what happens with the boards that remain
  after this removal, but I expect to revisit this in the future, and
  with most boards gone, there will be a good time to do a treewide
  review of platform drivers that never gained DT support and have no
  remaining in-tree board files"

Pull ARM DT updates from Arnd Bergmann:
 "As usual, the bulk of the changes for the SoC tree are devicetree file
  updates, and most of these changes are for 64-bit embedded machines.
  As before, there are a ton of style cleanups, and additional hardware
  support for existing machines.

  Looking only at the new SoC, the notable additions are:

   - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
     BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
     BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
     with a corresponding reference board.

   - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
     i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
     NPU.

   - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
     Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
     SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
     added here in addition to the reference boards.

   - Allwinner H616, a newer version of the H6 SoC, targeted at
     Set-top-box applications. It comes with dts files for the Orange Pi
     zero2 single-board computer and the X96 Mate set-top-box

   - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the
     Armada SoC family based on the Cortex-A55 core.

  New machines based on previously supported SoCs include:

   - Several new machines on NXP i.MX platforms: multiple Toradex
     Colibri boards using the "Iris" and "Ixora" carriers, DH
     electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and
     phytech phyBOARD-Polis-i.MX8MM.

   - Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix
     10 Software Virtual platform, both in the SoCFPGA platform.

   - Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000
     Router and the Cisco Meraki MR26 access point

   - Improved Chromebook support for both the Mediatek and Qualcomm SoC
     families brought added machines: Acer Chromebook 514 (MT8192), Acer
     Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines
     including the Lenovo IdeaPad Chromebook Duet 3.

   - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
     Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.

   - Finally, there are a few development board on other chips: PCB8309
     (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC
     Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660)"

Pull scheduler updates from Ingo Molnar:
"Load-balancing improvements:

   - Improve NUMA balancing on AMD Zen systems for affine workloads.

   - Improve the handling of reduced-capacity CPUs in load-balancing.

   - Energy Model improvements: fix & refine all the energy fairness
     metrics (PELT), and remove the conservative threshold requiring 6%
     energy savings to migrate a task. Doing this improves power
     efficiency for most workloads, and also increases the reliability
     of energy-efficiency scheduling.

   - Optimize/tweak select_idle_cpu() to spend (much) less time
     searching for an idle CPU on overloaded systems. There's reports of
     several milliseconds spent there on large systems with large
     workloads ...

     [ Since the search logic changed, there might be behavioral side
       effects. ]

   - Improve NUMA imbalance behavior. On certain systems with spare
     capacity, initial placement of tasks is non-deterministic, and such
     an artificial placement imbalance can persist for a long time,
     hurting (and sometimes helping) performance.

     The fix is to make fork-time task placement consistent with runtime
     NUMA balancing placement.

     Note that some performance regressions were reported against this,
     caused by workloads that are not memory bandwith limited, which
     benefit from the artificial locality of the placement bug(s). Mel
     Gorman's conclusion, with which we concur, was that consistency is
     better than random workload benefits from non-deterministic bugs:

        "Given there is no crystal ball and it's a tradeoff, I think
         it's better to be consistent and use similar logic at both fork
         time and runtime even if it doesn't have universal benefit."

   - Improve core scheduling by fixing a bug in
     sched_core_update_cookie() that caused unnecessary forced idling.

   - Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs
     for newly woken tasks.

   - Fix a newidle balancing bug that introduced unnecessary wakeup
     latencies.

  ABI improvements/fixes:

   - Do not check capabilities and do not issue capability check denial
     messages when a scheduler syscall doesn't require privileges. (Such
     as increasing niceness.)

   - Add forced-idle accounting to cgroups too.

   - Fix/improve the RSEQ ABI to not just silently accept unknown flags.
     (No existing tooling is known to have learned to rely on the
     previous behavior.)

   - Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.

  Optimizations:

   - Optimize & simplify leaf_cfs_rq_list()

   - Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().

  Misc fixes & cleanups:

   - Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.

   - Fix a full-NOHZ bug that can in some cases result in the tick not
     being re-enabled when the last SCHED_RT task is gone from a
     runqueue but there's still SCHED_OTHER tasks around.

   - Various PREEMPT_RT related fixes.

Merge tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull acl updates from Christian Brauner:
 "Last cycle we introduced support for mounting overlayfs on top of
  idmapped mounts. While looking into additional testing we realized
  that posix acls don't really work correctly with stacking filesystems
  on top of idmapped layers.

  We already knew what the fix were but it would require work that is
  more suitable for the merge window so we turned off posix acls for
  v5.19 for overlayfs on top of idmapped layers with Miklos routing my
  patch upstream in 72a8e05d ("Merge tag 'ovl-fixes-5.19-rc7' [..]").

  This contains the work to support posix acls for overlayfs on top of
  idmapped layers. Since the posix acl fixes should use the new
  vfs{g,u}id_t work the associated branch has been merged in. (We sent a
  pull request for this earlier.)

  We've also pulled in Miklos pull request containing my patch to turn
  of posix acls on top of idmapped layers. This allowed us to avoid
  rebasing the branch which we didn't like because we were already at
  rc7 by then. Merging it in allows this branch to first fix posix acls
  and then to cleanly revert the temporary fix it brought in by commit
  4a47c638 ("ovl: turn of SB_POSIXACL with idmapped layers
  temporarily").

  The last patch in this series adds Seth Forshee as a co-maintainer for
  idmapped mounts. Seth has been integral to all of this work and is
  also the main architect behind the filesystem idmapping work which
  ultimately made filesystems such as FUSE and overlayfs available in
  containers. He continues to be active in both development and review.
  I'm very happy he decided to help and he has my full trust. This
  increases the bus factor which is always great for work like this. I'm
  honestly very excited about this because I think in general we don't
  do great in the bringing on new maintainers department"

Pull fs idmapping updates from Christian Brauner:
 "This introduces the new vfs{g,u}id_t types we agreed on. Similar to
  k{g,u}id_t the new types are just simple wrapper structs around
  regular {g,u}id_t types.

  They allow to establish a type safety boundary in the VFS for idmapped
  mounts preventing confusion betwen {g,u}ids mapped into an idmapped
  mount and {g,u}ids mapped into the caller's or the filesystem's
  idmapping.

  An initial set of helpers is introduced that allows to operate on
  vfs{g,u}id_t types. We will remove all references to non-type safe
  idmapped mounts helpers in the very near future. The patches do
  already exist.

  This converts the core attribute changing codepaths which become
  significantly easier to reason about because of this change.

  Just a few highlights here as the patches give detailed overviews of
  what is happening in the commit messages:

   - The kernel internal struct iattr contains type safe vfs{g,u}id_t
     values clearly communicating that these values have to take a given
     mount's idmapping into account.

   - The ownership values placed in struct iattr to change ownership are
     identical for idmapped and non-idmapped mounts going forward. This
     also allows to simplify stacking filesystems such as overlayfs that
     change attributes In other words, they always represent the values.

   - Instead of open coding checks for whether ownership changes have
     been requested and an actual update of the inode is required we now
     have small static inline wrappers that abstract this logic away
     removing a lot of code duplication from individual filesystems that
     all open-coded the same checks"

   The recently added midcomms warnings are much more useful.

The unhold_lkb() function decrements the lock's kref, and
asserts that the ref count was not the final one.  Use the
kref_put release function (which should not be called) to
call the assert, rather than doing the assert based on the
kref_put return value.  Using kill_lkb() as the release
function doesn't make sense if we only want to assert.

This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option
that must be enabled to use two timeout-related features
that we intend to remove in kernel v6.2.  Warnings are
printed if either is enabled and used.  Neither has ever
been used as far as we know.

. The DLM_LSFL_TIMEWARN lockspace creation flag will be
  removed, along with the associated configfs entry for
  setting the timeout.  Setting the flag and configfs file
  would cause dlm to track how long locks were waiting
  for reply messages.  After a timeout, a kernel message
  would be logged, and a netlink message would be sent
  to userspace.  Recently, midcomms messages have been
  added that produce much better logging about actual
  problems with messages.  No use has ever been found
  for the netlink messages.

. The userspace libdlm API has allowed the DLM_LKF_TIMEOUT
  flag with a timeout value to be set in lock requests.
  The lock request would be cancelled after the timeout.

rseq_abi()->flags and rseq_abi()->rseq_cs->flags 29 upper bits are
currently unused.

The current behavior when those bits are set is to ignore them. This is
not an ideal behavior, because when future features will start using
those flags, if user-space fails to correctly validate that the kernel
indeed supports those flags (e.g. with a new sys_rseq flags bit) before
using them, it may incorrectly assume that the kernel will handle those
flags way when in fact those will be silently ignored on older kernels.

Validating that unused flags bits are cleared will allow a smoother
transition when those flags will start to be used by allowing
applications to fail early, and obviously, when they attempt to use the
new flags on an older kernel that does not support them.

The pretty much unused RSEQ_CS_FLAG_NO_RESTART_ON_* flags introduce
complexity in rseq, and are subtly buggy [1]. Solving those issues
requires introducing additional complexity in the rseq implementation
for each supported architecture.

Considering that it complexifies the rseq ABI, I am proposing that we
deprecate those flags. [2]

So far there appears to be consensus from maintainers of user-space
projects impacted by this feature that its removal would be a welcome
simplification. [3]

The deprecation approach proposed here is to issue WARN_ON_ONCE() when
encountering those flags and kill the offending process with sigsegv.
This should allow us to quickly identify whether anyone yells at us for
removing this.
