#     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"
