Hi Linus,

Please pull the arm64 fixes below based on top of the previous arm64
pull request. It's mostly PMU fixes and a reworking of the pseudo-NMI
disabling on broken MediaTek firmware (we didn't have time to do it
before the merging window). Thanks.

The following changes since commit 14dcf78a6c042dd9421b11485b394c6273568bca:

  Merge branch 'for-next/cpus_have_const_cap' into for-next/core (2023-10-26 17:10:18 +0100)

  arm64/syscall: Remove duplicate declaration (2023-11-09 17:19:14 +0000)

----------------------------------------------------------------
arm64 fixes:

- 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.
