From: Thomas Huth <address@hidden>
The real-to-absolute address translation in mmu_translate() was
missing the second part for translating the page at the prefix
address back to the 0 page. And while we're at it, also moved the
code into a separate helper function since this might come in
handy for other parts of the code, too.
