Instead it declared an alias for the non-existent paes algorithm. The Crypto API will eventually try to load the paes algorithm, to construct the cbc(paes) instance. But because the module does not actually contain a "paes" algorithm, this will fail. Previously this failure was hidden and the the cbc(paes) lookup will be retried. This was fixed recently, thus exposing the buggy alias in paes_s390. Replace the bogus paes alias with aliases for the actual algorithms.
