Merge tag 'efi-fixes-for-v6.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi

Pull EFI fixes from Ard Biesheuvel:
 "Another small set of EFI fixes. Only the x86 one is likely to affect
  any actual users (and has a cc:stable), but the issue it fixes was
  only observed in an unusual context (kexec in a confidential VM).

   - Ensure that EFI runtime services are not unmapped by PAN on ARM

   - Avoid freeing the memory holding the EFI memory map inadvertently
     on x86

   - Avoid a false positive kmemleak warning on arm64"
