Merge tag 'efi-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/mfleming/efi into x86/urgent
Pull EFI fixes from Matt Fleming: "* Fix EFI boot regression introduced during the merge window where the firmware was reading random values from the stack because we were passing a pointer to the wrong object type. * Kernel corruption has been reported when booting with the EFI boot stub which was tracked down to setting a bogus value for bp->hdr.code32_start, resulting in corruption during relocation. * Olivier Martin reported that the wrong file handles were being passed to efi_file_(read|close), which works for x86 by luck due to the way that the FAT driver is implemented, but doesn't work on ARM."
