mm/page_alloc: combine __alloc_pages and __alloc_pages_nodemask
There are only two callers of __alloc_pages() so prune the thicket of alloc_page variants by combining the two functions together. Current callers of __alloc_pages() simply add an extra 'NULL' parameter and current callers of __alloc_pages_nodemask() call __alloc_pages() instead.
