set_pageblock_order() is a standalone function which sets pageblock_order, while current implementation calls this function on each ZONE of each node in free_area_init_core(). Since free_area_init_node() is the only user of free_area_init_core(), this patch moves set_pageblock_order() up one level to invoke set_pageblock_order() only once on each node.
