The patch titled
setup_per_zone_pages_min(): take zone->lock instead of zone->lru_lock

setup_per_zone_pages_min-take-zone-lock-instead-of-zone-lru_lock.patch

Subject: setup_per_zone_pages_min(): take zone->lock instead of zone->lru_lock
From: Gerald Schaefer <gerald.schaefer@xxxxxxxxxx>
This replaces zone->lru_lock in setup_per_zone_pages_min() with zone->lock.
There seems to be no need for the lru_lock anymore, but there is a need for
zone->lock instead, because that function may call move_freepages() via
setup_zone_migrate_reserve().
