      Pull timer updates from Thomas Gleixner:
       "Time and clocksource/clockevent related updates:
      
        Core changes:
      
         - Infrastructure to support per CPU "broadcast" devices for per CPU
           clockevent devices which stop in deep idle states. This allows us
           to utilize the more efficient architected timer on certain ARM SoCs
           for normal operation instead of permanentely using the slow to
           access SoC specific clockevent device.
      
         - Print the name of the broadcast/wakeup device in /proc/timer_list
      
         - Make the clocksource watchdog more robust against delays between
           reading the current active clocksource and the watchdog
           clocksource. Such delays can be caused by NMIs, SMIs and vCPU
           preemption.
      
           Handle this by reading the watchdog clocksource twice, i.e. before
           and after reading the current active clocksource. In case that the
           two watchdog reads shows an excessive time delta, the read sequence
           is repeated up to 3 times.
      
         - Improve the debug output and add a test module for the watchdog
           mechanism.
      
         - Reimplementation of the venerable time64_to_tm() function with a
           faster and significantly smaller version. Straight from the source,
           i.e. the author of the related research paper contributed this!
      
        Driver changes:
      
         - No new drivers, not even new device tree bindings!
      
         - Fixes, improvements and cleanups and all over the place"

      Pull irq updates from Thomas Gleixner:
       "Updates for the interrupt subsystem:
      
        Core changes:
      
         - Cleanup and simplification of common code to invoke the low level
           interrupt flow handlers when this invocation requires irqdomain
           resolution. Add the necessary core infrastructure.
      
         - Provide a proper interface for modular PMU drivers to set the
           interrupt affinity.
      
         - Add a request flag which allows to exclude interrupts from spurious
           interrupt detection. Useful especially for IPI handlers which
           always return IRQ_HANDLED which turns the spurious interrupt
           detection into a pointless waste of CPU cycles.
      
        Driver changes:
      
         - Bulk convert interrupt chip drivers to the new irqdomain low level
           flow handler invocation mechanism.

      Pull CPU hotplug fix from Thomas Gleixner:
       "A fix for the CPU hotplug and cpusets interaction:
      
        cpusets delegate the hotplug work to a workqueue to prevent a lock
        order inversion vs. the CPU hotplug lock. The work is not flushed
        before the hotplug operation returns which creates user visible
        inconsistent state. Prevent this by flushing the work after dropping

      Pull printk updates from Petr Mladek:
      
       - Add %pt[RT]s modifier to vsprintf(). It overrides ISO 8601 separator
         by using ' ' (space). It produces "YYYY-mm-dd HH:MM:SS" instead of
         "YYYY-mm-ddTHH:MM:SS".
      
       - Correctly parse long row of numbers by sscanf() when using the field
         width. Add extensive sscanf() selftest.
      
       - Generalize re-entrant CPU lock that has already been used to
         serialize dump_stack() output. It is part of the ongoing printk
         rework. It will allow to remove the obsoleted printk_safe buffers and
         introduce atomic consoles.
      
       - Some code clean up and sparse warning fixes.

       "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.

      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"
