Herbert Xu 73c2437109 crypto: s390/sha3 - Use cpu byte-order when exporting
The sha3 partial hash on s390 is in little-endian just like the
final hash.  However the generic implementation produces native
or big-endian partial hashes.

Make s390 sha3 conform to that by doing the byte-swap on export
and import.
