[PATCH 4/4] mm, page_alloc: optimize batch count in free_pcppages_bulk()

If we use a division operation, we can compute a batch count more closed to ideal value. With this value, we can finish our job within MIGRATE_PCPTYPES iteration. In addition, batching to free more pages may be helpful to cache usage. Signed-off-by: Joonsoo Kim diff --git a/mm/page_alloc.c
