Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 fixes from Will Deacon:
 "The important one is a change to the way in which we handle protection
  keys around signal delivery so that we're more closely aligned with
  the x86 behaviour, however there is also a revert of the previous fix
  to disable software tag-based KASAN with GCC, since a workaround
  materialised shortly afterwards.

  I'd love to say we're done with 6.12, but we're aware of some
  longstanding fpsimd register corruption issues that we're almost at
  the bottom of resolving.

  Summary:

   - Fix handling of POR_EL0 during signal delivery so that pushing the
     signal context doesn't fail based on the pkey configuration of the
     interrupted context and align our user-visible behaviour with that
     of x86.

   - Fix a bogus pointer being passed to the CPU hotplug code from the
     Arm SDEI driver.

   - Re-enable software tag-based KASAN with GCC by using an alternative
     implementation of '__no_sanitize_address'"
