Pull power management updates from Rafael Wysocki:
 "These add hybrid processors support to the intel_pstate driver and
  make it work with more processor models when HWP is disabled, make the
  intel_idle driver use special C6 idle state paremeters when package
  C-states are disabled, add cooling support to the tegra30 devfreq
  driver, rework the TEO (timer events oriented) cpuidle governor,
  extend the OPP (operating performance points) framework to use the
  required-opps DT property in more cases, fix some issues and clean up
  a number of assorted pieces of code.

  Specifics:

   - Make intel_pstate support hybrid processors using abstract
     performance units in the HWP interface (Rafael Wysocki).

   - Add Icelake servers and Cometlake support in no-HWP mode to
     intel_pstate (Giovanni Gherdovich).

   - Make cpufreq_online() error path be consistent with the CPU device
     removal path in cpufreq (Rafael Wysocki).

   - Clean up 3 cpufreq drivers and the statistics code (Hailong Liu,
     Randy Dunlap, Shaokun Zhang).

   - Make intel_idle use special idle state parameters for C6 when
     package C-states are disabled (Chen Yu).

   - Rework the TEO (timer events oriented) cpuidle governor to address
     some theoretical shortcomings in it (Rafael Wysocki).

   - Drop unneeded semicolon from the TEO governor (Wan Jiabing).

   - Modify the runtime PM framework to accept unassigned suspend and
     resume callback pointers (Ulf Hansson).

   - Improve pm_runtime_get_sync() documentation (Krzysztof Kozlowski).

   - Improve device performance states support in the generic power
     domains (genpd) framework (Ulf Hansson).

   - Fix some documentation issues in genpd (Yang Yingliang).

   - Make the operating performance points (OPP) framework use the
     required-opps DT property in use cases that are not related to
     genpd (Hsin-Yi Wang).

   - Make lazy_link_required_opp_table() use list_del_init instead of
     list_del/INIT_LIST_HEAD (Yang Yingliang).

   - Simplify wake IRQs handling in the core system-wide sleep support
     code and clean up some coding style inconsistencies in it (Tian
     Tao, Zhen Lei).

   - Add cooling support to the tegra30 devfreq driver and improve its
     DT bindings (Dmitry Osipenko).

   - Fix some assorted issues in the devfreq core and drivers (Chanwoo
     Choi, Dong Aisheng, YueHaibing)"

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!

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.

   - Add device tree bindings for the Renesas R-Car M3-W+ SoC

   - Enable modular build of the Qualcomm PDC driver

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
  CPU hotplug lock and before releasing the outer mutex which serializes

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 integrity subsystem updates from Mimi Zohar:
 "The large majority of the changes are EVM portable & immutable
  signature related: removing a dependency on loading an HMAC key,
  safely allowing file metadata included in the EVM portable & immutable
  signatures to be modified, allowing EVM signatures to fulfill IMA file
  signature policy requirements, including the EVM file metadata
  signature in lieu of an IMA file data signature in the measurement
  list, and adding dynamic debugging of EVM file metadata.

  In addition, in order to detect critical data or file change
  reversions, duplicate measurement records are permitted in the IMA
  measurement list.

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"
