Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi into efi/urgent
Pull another handful of EFI fixes for v5.2 from Arnd:
- Fix a potential crash after kexec on arm64 with GICv3
- Fix a build warning on x86
- Stop policing the BGRT feature flags
- Use a non-blocking version of SetVariable() in the boot control driver
