[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.
