    Old code aligned it to 8-bytes.
    There is 50/50-chance of it also being 16-byte aligned.
    So it ended up being both 8-byte and 16-byte aligned.

    I haven't spotted brokenness in Linux microcode loader other
    than that small alignment issue.

    However, I can confirm that there are 2 microcode updates newer
    than what my laptop computer's latest BIOS includes. Both newer
    ones (20191115 and 20191112) are unstable on my laptop computer
    i5-7200U (fam 6 model 142 step 9 pf 0x80). Hard lockups with both
    of them. Back to BIOS microcode for now.
