e50944e219 crypto: shash - remove useless setting of type flags 
Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH.  But this
is redundant with the C structure type ('struct shash_alg'), and
crypto_register_shash() already sets the type flag automatically,
clearing any type flag that was already there.  Apparently the useless
assignment has just been copy+pasted around.

So, remove the useless assignment from all the shash algorithms.

This patch shouldn't change any actual behavior.

5d26a105b5 crypto: prefix module autoloading with "crypto-" 
This prefixes all crypto module loading with "crypto-" so we never run
the risk of exposing module auto-loading to userspace via a crypto API,
as demonstrated by Mathias Krause:

5cdcc22f25 [CRYPTO] rmd: Use pointer form of endian swapping operations 
This patch converts the relevant code in the rmd implementations to
use the pointer form of the endian swapping operations.  This allows
certain architectures to generate more optimised code.  For example,
on sparc64 this more than halves the CPU cycles on a typical hashing
operation.

Based on a patch by David Miller.
