Subject: [GIT PULL] arm64 updates for 5.7
Hi Linus,
Please pull the arm64 updates below. 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.
Thanks.
The following changes since commit f8788d86ab28f61f7b46eb6be375f8a726783636:

mm/mremap: Add comment explaining the untagging behaviour of mremap() (2020-03-26 11:28:57 +0000)
----------------------------------------------------------------
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.
