New Revision: 323868
URL: https://svnweb.freebsd.org/changeset/base/323868

Log:
  Modernize calls to vm_page_unwire().  As of r288122, vm_page_unwire()
  accepts PQ_NONE as the specified queue and returns a Boolean indicating
  whether the page's wire count transitioned to zero.  Use these features
  in dev/drm2.
