For the next revision, can you ditch the '_nodemask' part of the name?
Andrew just took this patch from me:

    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.

...

-__alloc_pages_nodemask(gfp_t gfp_mask, unsigned int order, int preferred_nid,
-                                                       nodemask_t *nodemask);
-
-static inline struct page *
-__alloc_pages(gfp_t gfp_mask, unsigned int order, int preferred_nid)
-{
-       return __alloc_pages_nodemask(gfp_mask, order, preferred_nid, NULL);
-}
+struct page *__alloc_pages(gfp_t gfp, unsigned int order, int preferred_nid,
+               nodemask_t *nodemask);

So calling this function __alloc_pages_bulk() fits with the new naming
scheme.

Also I renamed alloc_mask to alloc_gfp.
