Linus Torvalds 9840cfcb97 arm64 updates for 5.14
- 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.

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

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"
