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.
