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

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
