  SVN rev 190275 on 2009-03-22 20:46:37Z by alc
  
  MFC r188932, r189785, r189795, and r190272
    Optimize free_pv_entry(); specifically, avoid repeated TAILQ_REMOVE()s.
  
    Update the pmap's resident page count when a page table page is freed in
    pmap_remove_pde() and pmap_remove_pages().
  
    Update stale comments.  The alternate address space mapping was eliminated
    when PAE support was added to i386.  The direct mapping exists on amd64.
