With ARCH=arm, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in lib/crypto/libsha256.o
Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().
This includes sha1.c and utils.c which, although they did not produce
a warning with the arm allmodconfig configuration, may cause this
warning with other configurations.

The utilities have historically resided in algapi.h as they were
first used internally before being exported. Move them into a
new header file so external users don't see internal API details.

CRYPTO_LIB_CHACHA depends on CRYPTO for __crypto_xor, defined in
crypto/algapi.c. This is a layering violation because the dependencies
should only go in the other direction (crypto/ => lib/crypto/). Also
the correct dependency would be CRYPTO_ALGAPI, not CRYPTO. Fix this by
moving __crypto_xor into the utils module in lib/crypto/.
Note that CRYPTO_LIB_CHACHA_GENERIC selected XOR_BLOCKS, which is
unrelated and unnecessary. It was perhaps thought that XOR_BLOCKS was
needed for __crypto_xor, but that's not the case.
