Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 updates from Catalin Marinas:
 "Notable features are user-space support for the memcpy/memset
  instructions and the permission indirection extension.

   - Support for the Armv8.9 Permission Indirection Extensions. While
     this feature doesn't add new functionality, it enables future
     support for Guarded Control Stacks (GCS) and Permission Overlays

   - User-space support for the Armv8.8 memcpy/memset instructions

   - arm64 perf: support the HiSilicon SoC uncore PMU, Arm CMN sysfs
     identifier, support for the NXP i.MX9 SoC DDRC PMU, fixes and
     cleanups

   - Removal of superfluous ISBs on context switch (following
     retrospective architecture tightening)

   - Decode the ISS2 register during faults for additional information
     to help with debugging

   - KPTI clean-up/simplification of the trampoline exit code

   - Addressing several -Wmissing-prototype warnings

   - Kselftest improvements for signal handling and ptrace

   - Fix TPIDR2_EL0 restoring on sigreturn

   - Clean-up, robustness improvements of the module allocation code

   - More sysreg conversions to the automatic register/bitfields
     generation

   - CPU capabilities handling cleanup

   - Arm documentation updates: ACPI, ptdump"
