Merge branch 'x86-efi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pul x86/efi changes from Ingo Molnar:
"This tree adds an EFI bootloader handover protocol, which, once
supported on the bootloader side, will make bootup faster and might
result in simpler bootloaders.
The other change activates the EFI wall clock time accessors on x86-64
as well, instead of the legacy RTC readout."
