Hmm, I have a couple of small concerns.

First, I'm not sure if the name is clear enough for a public function.

Second, I'm not sure if mmu-hash64.h is the right place for it.  This
is still a function with very specific and limited usage, I wonder if
we should have somewhere else for such special real mode helpers.

Paulus, thoughts?
