  SVN rev 206770 on 2010-04-17 21:14:37Z by alc
  
  In vm_object_madvise() setting PG_REFERENCED on a page before sleeping on
  that page only makes sense if the advice is MADV_WILLNEED.  In that case,
  the intention is to activate the page, so discouraging the page daemon
  from reclaiming the page makes sense.  In contrast, in the other cases,
  MADV_DONTNEED and MADV_FREE, it makes no sense whatsoever to discourage
  the page daemon from reclaiming the page by setting PG_REFERENCED.
  
  Wrap a nearby line.
