Rename pmap_collect() to pmap_pv_reclaim() and rewrite it such that it no longer uses the active and inactive paging queues. Eliminate some purely stylistic differences among the amd64, i386 native, and i386 xen PV entry allocators. Eliminate code duplication in free_pv_entry() and pmap_remove_pages() by introducing free_pv_chunk(). END
