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" * 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/efi: Don't unmap EFI boot services code/data regions for EFI_OLD_MEMMAP and EFI_MIXED_MODE efi: Reduce the amount of memblock reservations for persistent allocations efi: Permit multiple entries in persistent memreserve data structure efi/libstub: Disable some warnings for x86{,_64} x86/efi: Move efi_<reserve/free>_boot_services() to arch/x86 x86/efi: Unmap EFI boot services code/data regions from efi_pgd x86/mm/pageattr: Introduce helper function to unmap EFI boot services efi/fdt: Simplify the get_fdt() flow efi/fdt: Indentation fix firmware/efi: Add NULL pointer checks in efivars API functions
