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 EFI changes in this cycle were: - Use 32-bit alignment for efi_guid_t - Allow the SetVirtualAddressMap() call to be omitted - Implement earlycon=efifb based on existing earlyprintk code - Various minor fixes and code cleanups from Sai, Ard and me" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi: Fix build error due to enum collision between efi.h and ima.h efi/x86: Convert x86 EFI earlyprintk into generic earlycon implementation x86: Make ARCH_USE_MEMREMAP_PROT a generic Kconfig symbol efi/arm/arm64: Allow SetVirtualAddressMap() to be omitted efi: Replace GPL license boilerplate with SPDX headers efi/fdt: Apply more cleanups efi: Use 32-bit alignment for efi_guid_t efi/memattr: Don't bail on zero VA if it equals the region's PA x86/efi: Mark can_free_region() as an __init function
