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:
- Changes to the EFI init code to establish whether secure boot
authentication was performed at boot time. (Josh Boyer, David
Howells)
- Wire up the UEFI memory attributes table for x86. This eliminates
any runtime memory regions that are both writable and executable,
on recent firmware versions. (Sai Praneeth)
- Move the BGRT init code to an earlier stage so that we can still
use efi_mem_reserve(). (Dave Young)
- Preserve debug symbols in the ARM/arm64 UEFI stub (Ard Biesheuvel)
- Code deduplication work and various other cleanups (Lukas Wunner)
- ... plus various other fixes and cleanups"
