It's getting into shape, but it has a slight shortage of reviews. For
now, it's an all-Intel patch even though I _thought_ AMD had this
feature too. It's also purely for KVM and has some suggested-by's from
Sean, but no KVM acks on it.

I have the feeling Sean would speak up if this was going in a bad
direction for KVM, but I do love to see acks accompanying suggested-by's
to indicate that the suggestion was interpreted properly.
