Justin Hibbits b2f831c009 Simplify the page tracking for VA<->PA translations.
Drop the tracking down to the pmap layer, with optimizations to only track
necessary pages.  This should give a (slight) performance improvement, as well
as a stability improvement, as the tracking is already mostly handled by the
pmap layer.
