[PATCH] page migration cleanup: drop nr_refs in remove_references()
Drop nr_refs parameter from migrate_page_remove_references() The nr_refs parameter is not really useful since the number of remaining references is always 1 for anonymous pages without a mapping 2 for pages with a mapping 3 for pages with a mapping and PagePrivate set. Remove the early check for the number of references since we are checking page_mapcount() earlier. Ultimately only the refcount matters after the tree_lock has been obtained.
