    Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux · 3d8dfe75
    Linus Torvalds authored
    Pull arm64 updates from Catalin Marinas:
    
     - Pseudo NMI support for arm64 using GICv3 interrupt priorities
    
     - uaccess macros clean-up (unsafe user accessors also merged but
       reverted, waiting for objtool support on arm64)
    
     - ptrace regsets for Pointer Authentication (ARMv8.3) key management
    
     - inX() ordering w.r.t. delay() on arm64 and riscv (acks in place by
       the riscv maintainers)
    
     - arm64/perf updates: PMU bindings converted to json-schema, unused
       variable and misleading comment removed
    
     - arm64/debug fixes to ensure checking of the triggering exception
       level and to avoid the propagation of the UNKNOWN FAR value into the
       si_code for debug signals
    
     - Workaround for Fujitsu A64FX erratum 010001
    
     - lib/raid6 ARM NEON optimisations
    
     - NR_CPUS now defaults to 256 on arm64
    
     - Minor clean-ups (documentation/comments, Kconfig warning, unused
       asm-offsets, clang warnings)
    
     - MAINTAINERS update for list information to the ARM64 ACPI entry
