Subject: [PATCH] mm/page_alloc: in zone_pcp_update(), uze zone_pageset_init()

Previously, zone_pcp_update() called pageset_set_batch() directly,
essentially assuming that percpu_pagelist_fraction == 0.

Correct this by calling zone_pageset_init(), which chooses the
appropriate ->batch and ->high calculations.
