History
Linus Torvalds 3cd86a58f7 arm64 updates for 5.7: 
- 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.

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"
