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

Pull arm64 updates from Catalin Marinas:
"The bulk is in-kernel pointer authentication, activity monitors and
lots of asm symbol annotations. I also queued the sys_mremap() patch
commenting the asymmetry in the address untagging.

Summary:

- In-kernel Pointer Authentication support (previously only offered
to user space).

- ARM Activity Monitors (AMU) extension support allowing better CPU
utilisation numbers for the scheduler (frequency invariance).

- Memory hot-remove support for arm64.

- Lots of asm annotations (SYM_*) in preparation for the in-kernel
Branch Target Identification (BTI) support.

- arm64 perf updates: ARMv8.5-PMU 64-bit counters, refactoring the
PMU init callbacks, support for new DT compatibles.

- IPv6 header checksum optimisation.

- Fixes: SDEI (software delegated exception interface) double-lock on
hibernate with shared events.

- Minor clean-ups and refactoring: cpu_ops accessor,
cpu_do_switch_mm() converted to C, cpufeature finalisation helper.

- sys_mremap() comment explaining the asymmetric address untagging
behaviour"

arm64: Introduce get_cpu_ops() helper function

This introduces get_cpu_ops() to return the CPU operations according to
the given CPU index. For now, it simply returns the @cpu_ops[cpu] as
before. Also, helper function __cpu_try_die() is introduced to be shared
by cpu_die() and ipi_cpu_crash_stop(). So it shouldn't introduce any
functional changes.
