Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
"Mostly PMU fixes and a reworking of the pseudo-NMI disabling on broken
MediaTek firmware:
- Move the MediaTek GIC quirk handling from irqchip to core. Before
the merging window commit 44bd78dd2b88 ("irqchip/gic-v3: Disable
pseudo NMIs on MediaTek devices w/ firmware issues") temporarily
addressed this issue. Fixed now at a deeper level in the arch code
- Reject events meant for other PMUs in the CoreSight PMU driver,
otherwise some of the core PMU events would disappear
- Fix the Armv8 PMUv3 driver driver to not truncate 64-bit registers,
causing some events to be invisible
- Remove duplicate declaration of __arm64_sys##name following the
patch to avoid prototype warning for syscalls
- Typos in the elf_hwcap documentation"
