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 biggest change in this cycle was the addition of ARM CPER error

There are also misc smaller updates: documentation update, cleanups
and an EFI memory map permissions quirk"
