  SVN rev 196894 on 2009-09-06 15:23:03Z by kib
  
  Partial MFC of r194459 by thompsa, without merge recording,
  to allow the vm_phys_paddr_to_vm_page(9) to return NULL instead
  of panicking when supplied physical address does not correspond
  to a vm page. This is needed for device pager (and not yet merged
  sg pager) to skip memattr checks on specific addresses.
