SVN rev 208044 on 2010-05-13 20:26:16Z by kib
MFC elimination of several settings of PG_REFERENCED bit, that either
do not make sense or are harmful.
MFC r206761 (by alc):
Setting PG_REFERENCED on the requested page in swap_pager_getpages() is
either redundant or harmful, depending on the caller.
MFC r206768 (by alc):
In vm_object_backing_scan(), setting PG_REFERENCED on a page before
sleeping on that page is nonsensical.
MFC r206770 (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.
MFC r206801 (by alc):
There is no justification for vm_object_split() setting PG_REFERENCED on a
page that it is going to sleep on.
