#     Fix built-in early-load Intel microcode alignment
#     
#     Intel Software Developer's Manual, volume 3, chapter 9.11.6 says:
#     
#      "Note that the microcode update must be aligned on a 16-byte boundary
#       and the size of the microcode update must be 1-KByte granular"
#     
#     When early-load Intel microcode is loaded from initramfs, userspace tool
#     'iucode_tool' has already 16-byte aligned those microcode bits in that
#     initramfs image.  Image that was created something like this:
#     
#      iucode_tool --write-earlyfw=FOO.cpio microcode-files...
#     
#     However, when early-load Intel microcode is loaded from built-in
#     firmware BLOB using CONFIG_EXTRA_FIRMWARE= kernel config option, that
#     16-byte alignment is not guaranteed.
#     
#     Fix this by forcing all built-in firmware BLOBs to 16-byte alignment.
#     
#     [ If we end up having other firmware with much bigger alignment
#       requirements, we might need to introduce some method for the firmware
#       to specify it, this is the minimal "just increase the alignment a bit
#       to account for this one special case" patch    - Linus ]
