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:

   - Allocate the E820 buffer before doing the
     GetMemoryMap/ExitBootServices dance so we don't run out of space

   - Clear EFI boot services mappings when freeing the memory

   - Harden efivars against callers that invoke it on non-EFI boots

   - Reduce the number of memblock reservations resulting from extensive
     use of the new efi_mem_reserve_persistent() API

   - Other assorted fixes and cleanups"
