Subject: [PATCH] [PATCH] vmscan: emove obsolete checks from shrink_list() and
 fix unlikely in refill_inactive_zone()

As suggested by Marcelo:

1. The optimization introduced recently for not calling
   page_referenced() during zone reclaim makes two additional checks in
   shrink_list unnecessary.

2. The if (unlikely(sc->may_swap)) in refill_inactive_zone is optimized
   for the zone_reclaim case.  However, most peoples system only does swap.
   Undo that.
