The page_test_and_clear_dirty primitive really consists of two operations, page_test_dirty and the page_clear_dirty. The combination of the two is not an atomic operation, so it makes more sense to have two separate operations instead of one. In addition to the improved readability of the s390 version of SetPageUptodate, it now avoids the page_test_dirty operation which is an insert-storage-key-extended (iske) instruction which is an expensive operation.
