Ok, good.

Peter, do you want to take it (feel free to add my sign-off), or
should I just commit it?

Also, is there a way to have a "likely not true" version of that
"static_cpu_has()"? There seems to be no way to make the non-K7/K8
case the fallthrough code.. Not that this is likely that
performance-critical, but..
