From: Eric Biggers <ebigg...@google.com>
Continue disentangling the crypto library functions from the generic
crypto infrastructure by moving the powerpc ChaCha and Poly1305 library
functions into a new directory arch/powerpc/lib/crypto/ that does not
depend on CRYPTO. This mirrors the distinction between crypto/ and
lib/crypto/.
