Pull documentation updates from Jonathan Corbet:
 "This was a reasonably active cycle for documentation; this includes:

   - Some kernel-doc cleanups. That script is still regex onslaught from
     hell, but it has gotten a little better.

   - Improvements to the checkpatch docs, which are also used by the
     tool itself.

   - A major update to the pathname lookup documentation.

   - Elimination of :doc: markup, since our automarkup magic can create
     references from filenames without all the extra noise.

   - The flurry of Chinese translation activity continues.

  Plus, of course, the usual collection of updates, typo fixes, and
  warning fixes"

Pull btrfs updates from David Sterba:
 "A normal mix of improvements, core changes and features that user have
  been missing or complaining about.

  User visible changes:

   - new sysfs exports:
      - add sysfs knob to limit scrub IO bandwidth per device
      - device stats are also available in
           /sys/fs/btrfs/FSID/devinfo/DEVID/error_stats

   - support cancellable resize and device delete ioctls

   - change how the empty value is interpreted when setting a property,
     so far we have only 'btrfs.compression' and we need to distinguish
     a reset to defaults and setting "do not compress", in general the
     empty value will always mean 'reset to defaults' for any other
     property, for compression it's either 'no' or 'none' to forbid
     compression

  Performance improvements:

   - no need for full sync when truncation does not touch extents,
     reported run time change is -12%

   - avoid unnecessary logging of xattrs during fast fsyncs (+17%
     throughput, -17% runtime on xattr stress workload)

  Core:

   - preemptive flushing improvements and fixes
      - adjust clamping logic on multi-threaded workloads to avoid
        flushing too soon
      - take into account global block reserve, may help on almost full
        filesystems
      - continue flushing when there are enough pending delalloc and
        ordered bytes

   - simplify logic around conditional transaction commit, a workaround
     used in the past for throttling that's been superseded by ticket
     reservations that manage the throttling in a better way

   - subpage blocksize preparation:
      - submit read time repair only for each corrupted sector
      - scrub repair now works with sectors and not pages
      - free space cache (v1) works with sectors and not pages
      - more fine grained bio tracking for extents
      - subpage support in page callbacks, extent callbacks, end io
        callbacks

   - simplify transaction abort logic and always abort and don't check
     various potentially unreliable stats tracked by the transaction

   - exclusive operations can do more checks when started and allow eg.
     cancellation of the same running operation

   - ensure relocation never runs while we have send operations running,
     e.g. when zoned background auto reclaim starts

  Fixes:

   - zoned: more sanity checks of write pointer

   - improve error handling in delayed inodes

   - send:
      - fix invalid path for unlink operations after parent
        orphanization
      - fix crash when memory allocations trigger reclaim

   - skip compression of we have only one page (can't make things
     better)

   - empty value of a property newly means reset to default

  Other:

   - lots of cleanups, comment updates, yearly typo fixing

   - disable build on platforms having page size 256K"

Pull arm64 updates from Will Deacon:
 "There's a reasonable amount here and the juicy details are all below.

  It's worth noting that the MTE/KASAN changes strayed outside of our
  usual directories due to core mm changes and some associated changes
  to some other architectures; Andrew asked for us to carry these [1]
  rather that take them via the -mm tree.

  Summary:

   - Optimise SVE switching for CPUs with 128-bit implementations.

   - Fix output format from SVE selftest.

   - Add support for versions v1.2 and 1.3 of the SMC calling
     convention.

   - Allow Pointer Authentication to be configured independently for
     kernel and userspace.

   - PMU driver cleanups for managing IRQ affinity and exposing event
     attributes via sysfs.

   - KASAN optimisations for both hardware tagging (MTE) and out-of-line
     software tagging implementations.

   - Relax frame record alignment requirements to facilitate 8-byte
     alignment with KASAN and Clang.

   - Cleanup of page-table definitions and removal of unused memory
     types.

   - Reduction of ARCH_DMA_MINALIGN back to 64 bytes.

   - Refactoring of our instruction decoding routines and addition of
     some missing encodings.

   - Move entry code moved into C and hardened against harmful compiler
     instrumentation.

   - Update booting requirements for the FEAT_HCX feature, added to v8.7
     of the architecture.

   - Fix resume from idle when pNMI is being used.

   - Additional CPU sanity checks for MTE and preparatory changes for
     systems where not all of the CPUs support 32-bit EL0.

   - Update our kernel string routines to the latest Cortex Strings
     implementation.

   - Big cleanup of our cache maintenance routines, which were
     confusingly named and inconsistent in their implementations.

   - Tweak linker flags so that GDB can understand vmlinux when using
     RELR relocations.

   - Boot path cleanups to enable early initialisation of per-cpu
     operations needed by KCSAN.

   - Non-critical fixes and miscellaneous cleanup"

    - Add "Core Scheduling" via CONFIG_SCHED_CORE=y, which enables
      coordinated scheduling across SMT siblings. This is a much
      requested feature for cloud computing platforms, to allow the
      flexible utilization of SMT siblings, without exposing untrusted
      domains to information leaks & side channels, plus to ensure more
      deterministic computing performance on SMT systems used by
      heterogenous workloads.

      There are new prctls to set core scheduling groups, which allows
      more flexible management of workloads that can share siblings.

    - Fix task->state access anti-patterns that may result in missed
      wakeups and rename it to ->__state in the process to catch new
      abuses.

 - Load-balancing changes:

    - Tweak newidle_balance for fair-sched, to improve 'memcache'-like
      workloads.

    - "Age" (decay) average idle time, to better track & improve
      workloads such as 'tbench'.

    - Fix & improve energy-aware (EAS) balancing logic & metrics.

    - Fix & improve the uclamp metrics.

    - Fix task migration (taskset) corner case on !CONFIG_CPUSET.

    - Fix RT and deadline utilization tracking across policy changes

    - Introduce a "burstable" CFS controller via cgroups, which allows
      bursty CPU-bound workloads to borrow a bit against their future
      quota to improve overall latencies & batching. Can be tweaked via
      /sys/fs/cgroup/cpu/<X>/cpu.cfs_burst_us.

    - Rework assymetric topology/capacity detection & handling.

 - Scheduler statistics & tooling:

    - Disable delayacct by default, but add a sysctl to enable it at
      runtime if tooling needs it. Use static keys and other
      optimizations to make it more palatable.

    - Use sched_clock() in delayacct, instead of ktime_get_ns().

 - Misc cleanups and fixes.

Pull locking updates from Ingo Molnar:

 - Core locking & atomics:

     - Convert all architectures to ARCH_ATOMIC: move every architecture
       to ARCH_ATOMIC, then get rid of ARCH_ATOMIC and all the
       transitory facilities and #ifdefs.

       Much reduction in complexity from that series:

           63 files changed, 756 insertions(+), 4094 deletions(-)

     - Self-test enhancements

 - Futexes:

     - Add the new FUTEX_LOCK_PI2 ABI, which is a variant that doesn't
       set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC).

       [ The temptation to repurpose FUTEX_LOCK_PI's implicit setting of
         FLAGS_CLOCKRT & invert the flag's meaning to avoid having to
         introduce a new variant was resisted successfully. ]

     - Enhance futex self-tests

 - Lockdep:

     - Fix dependency path printouts

     - Optimize trace saving

     - Broaden & fix wait-context checks

Dave Jones reported the following

	This made it into 5.13 final, and completely breaks NFSD for me
	(Serving tcp v3 mounts).  Existing mounts on clients hang, as do
	new mounts from new clients.  Rebooting the server back to rc7
	everything recovers.

The commit b3b64ebd ("mm/page_alloc: do bulk array bounds check after
checking populated elements") returns the wrong value if the array is
already populated which is interpreted as an allocation failure. Dave
reported this fixes his problem and it also passed a test running dbench
over NFS.
