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.
