Merge branch 'efi-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI fixes from Ingo Molnar: "A number of regression fixes: - Fix a boot hang on machines that have somewhat unusual memory map entries of phys_addr=0x0 num_pages=0, which broke due to a recent commit. This commit got cherry-picked from the v4.11 queue because the bug is affecting real machines. - Fix a boot hang also reported by KASAN, caused by incorrect init ordering introduced by a recent optimization. - Fix a recent robustification fix to allocate_new_fdt_and_exit_boot() that introduced an invalid assumption. Neither bugs were seen in the wild AFAIK" * 'efi-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: efi/x86: Prune invalid memory map entries and fix boot regression x86/efi: Don't allocate memmap through memblock after mm_init() efi/libstub/arm*: Pass latest memory map to the kernel
