Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull EFI updates from Ingo Molnar:
 "The main changes in this cycle were:

   - move BGRT handling to drivers/acpi so it can be shared between x86
     and ARM

   - bring the EFI stub's initrd and FDT allocation logic in line with
     the latest changes to the arm64 boot protocol

   - improvements and fixes to the EFI stub's command line parsing
     routines

   - randomize the virtual mapping of the UEFI runtime services on
     ARM/arm64

   - ... and other misc enhancements, cleanups and fixes"
