VMX "bypass_guest_pf" feature on prefetch_page breaks it (since new

Doesn't it kill bypass_guest_pf completely? As soon as we unsync a
page, we can't have nontrapping nonpresent ptes in it.
Yes, thats what I meant.
We can convert those ptes during unsync, and back during resync. That's
a fairly cheap operation.
