From: Vlastimil Babka <vbabka@xxxxxxx>
Subject: mm, page_isolation: drain single zone pcplists
When setting MIGRATETYPE_ISOLATE on a pageblock, pcplists are drained to
have a better chance that all pages will be successfully isolated and not
left in the per-cpu caches. Since isolation is always concerned with a
single zone, we can reduce the pcplists drain to the single zone, which is
now possible.
The change should make memory isolation faster and not disturbing
unrelated pcplists anymore.
