Merge tag 'efi-urgent' into x86/urgent
* The EFI variable anti-bricking algorithm merged in -rc8 broke booting
on some Apple machines because they implement EFI spec 1.10, which
doesn't provide a QueryVariableInfo() runtime function and the logic
used to check for the existence of that function was insufficient.
Fix from Josh Boyer.
* The anti-bricking algorithm also introduced a compiler warning on
32-bit. Fix from Borislav Petkov.
