Hi Linus,

Please pull another small set of EFI fixes below. 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).

The following changes since commit 99280413a5b785f22d91e8a8a66dc38f4a214495:

  efi: Add missing __nocfi annotations to runtime wrappers (2024-06-05 10:18:58 +0200)
