longer uses the active and inactive paging queues. Instead, the pmap now maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses this list to select pv entries for reclamation. Note: The old pmap_collect() tried to avoid reclaiming mappings for pages that have either a hold_count or a busy field that is non-zero. However, this isn't necessary for correctness, and the locking in pmap_collect() was insufficient to guarantee that such mappings weren't reclaimed. The new pmap_pv_reclaim() doesn't even try.
