Subject: [GIT PULL] arm64 updates for 5.1-rc1
Hi Linus,
Please pull the arm64 updates for 5.1 below. There is a minor conflict
with mainline in arch/arm64/Kconfig.platforms (with the changes from the
arm-soc tree); you can find my merge resolution at the end of this
email. The pull request touches riscv for the inX() ordering w.r.t.
delay() and the acks are in place.
Thanks,
Catalin
The following changes since commit 6e4933a006616343f66c4702dc4fc56bb25e7b02:

arm64: mmu: drop paging_init comments (2019-03-01 16:40:07 +0000)
----------------------------------------------------------------
arm64 updates for 5.1:
- 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
