From: Eric Biggers <ebigg...@google.com>
Continue disentangling the crypto library functions from the generic
crypto infrastructure by moving the s390 ChaCha library functions into a
new directory arch/s390/lib/crypto/ that does not depend on CRYPTO.
This mirrors the distinction between crypto/ and lib/crypto/.
