H A Dpmap.hdiff 228412 Sun Dec 11 15:34:33 MST 2011 nwhitehorn Keep track of PVO entries in each pmap, which allows much faster
pmap_remove() for large sparse requests. This can prevent pmap_remove()
operations on 64-bit process destruction or swapout that would take
several hundred times the lifetime of the universe to complete. This
behavior is largely indistinguishable from a hang.
