  SVN rev 208352 on 2010-05-20 16:21:19Z by alc
  
  MFC r207306
    Change vm_object_madvise() so that it checks whether the page is invalid
    or unmanaged before acquiring the page queues lock.  Neither of these
    tests require that lock.  Moreover, a better way of testing if the page
    is unmanaged is to test the type of vm object.  This avoids a pointless
    vm_page_lookup().
