Subject: [PATCH] mm: don't vmalloc a huge page_to_node array for
 do_pages_stat()

do_pages_stat() does not need any page_to_node entry for real.  Just pass
the pointers to the user-space page address array and to the user-space
status array, and have do_pages_stat() traverse the former and fill the
latter directly.
