Uhh, it has zero review comments on it. That's usually a pretty good reason.

It is a little worrying that this is even happening. Is there just a
single blip during boot when the MTRRs are "corrected" and then it's
never a problem again? Or is it causing latency blips all the time?

I do share some of Peter's concern that this is creaky, fragile,
lightly-used code and this series is mucking with it to work around a
BIOS issue.
