The X86_BUG_F00F work around is responsible for fixing up the error generated on attempted F00F exploitation from an OOPS to a SIGILL. There is no reason why this code should not be allowed to run on PV guest on a F00F-affected CPU -- it would simply never trigger. The pv_enabled() check was there only to avoid printing the f00f workaround, so removing the check is purely a cosmetic change.
