[GIT PULL] arm64 fixes for -rc6

[Will Deacon <will@kernel.org>]

Hi Linus,

Please pull these arm64 fixes for -rc6. We've had a steady trickle of
relatively minor fixes since -rc3 but they're all self-contained 6.16
material and confined to the arch code.

There's the usual summary in the tag.

Cheers,

Will

  arm64/mm: Drop wrong writes into TCR2_EL1 (2025-07-04 16:46:04 +0100)

----------------------------------------------------------------
arm64 fixes for -rc6

- Fix bogus KASAN splat on EFI runtime stack

- Select JUMP_LABEL unconditionally to avoid boot failure with pKVM
  and the legacy implementation of static keys

- Avoid touching GCS registers when 'arm64.nogcs' has been passed on the
  command-line

- Move a 'cpumask_t' off the stack in smp_send_stop()

- Don't advertise SME-related hwcaps to userspace when ID_AA64PFR1_EL1
  indicates that SME is not implemented

- Always check the VMA when handling an Overlay fault

- Avoid corrupting TCR2_EL1 during boot
