#     Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 updates from Catalin Marinas:
#     
#      - arm64 perf: DDR PMU driver for Alibaba's T-Head Yitian 710 SoC, SVE
#        vector granule register added to the user regs together with SVE perf
#        extensions documentation.
#     
#      - SVE updates: add HWCAP for SVE EBF16, update the SVE ABI
#        documentation to match the actual kernel behaviour (zeroing the
#        registers on syscall rather than "zeroed or preserved" previously).
#     
#      - More conversions to automatic system registers generation.
#     
#      - vDSO: use self-synchronising virtual counter access in gettimeofday()
#        if the architecture supports it.
#     
#      - arm64 stacktrace cleanups and improvements.
#     
#      - arm64 atomics improvements: always inline assembly, remove LL/SC
#        trampolines.
#     
#      - Improve the reporting of EL1 exceptions: rework BTI and FPAC
#        exception handling, better EL1 undefs reporting.
#     
#      - Cortex-A510 erratum 2658417: remove BF16 support due to incorrect
#        result.
#     
#      - arm64 defconfig updates: build CoreSight as a module, enable options
#        necessary for docker, memory hotplug/hotremove, enable all PMUs
#        provided by Arm.
#     
#      - arm64 ptrace() support for TPIDR2_EL0 (register provided with the SME
#        extensions).
#     
#      - arm64 ftraces updates/fixes: fix module PLTs with mcount, remove
#        unused function.
#     
#      - kselftest updates for arm64: simple HWCAP validation, FP stress test
#        improvements, validation of ZA regs in signal handlers, include
#        larger SVE and SME vector lengths in signal tests, various cleanups.
#     
#      - arm64 alternatives (code patching) improvements to robustness and
#        consistency: replace cpucap static branches with equivalent
#        alternatives, associate callback alternatives with a cpucap.
#     
#      - Miscellaneous updates: optimise kprobe performance of patching
#        single-step slots, simplify uaccess_mask_ptr(), move MTE registers
#        initialisation to C, support huge vmalloc() mappings, run softirqs on
#        the per-CPU IRQ stack, compat (arm32) misalignment fixups for
#        multiword accesses.
