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"
