Merge branch x86/build into x86/efi and fix up arch/x86/boot/tools/build.c
Reason for merge: The updates to the EFI boot stub generation conflicted with the changes to properly use the get/put_unaligned_le*() macros to generate images. This merge commit completes the conversion in arch/x86/boot/tools/build.c including the places in the code which had been changed on the x86/efi branch. Resolved Conflicts: arch/x86/boot/tools/build.c Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
