Standardise both in-kernel and loaded firmware to be stored as
little-endian instead of host-endian.
Signed-off-by: David Woodhouse <dwmw2@infradead.org>
The maestro3 driver is byte-swapping its firmware to be host-endian in
advance, when it doesn't seem to be necessary -- we could just use
le16_to_cpu() as we load it.
Doing that means that we need to switch the in-tree firmware to be
little-endian too.
Take the least intrusive way of doing this, which is to switch the
existing snd_m3_convert_from_le() function to convert _to_ little-endian
instead, and use it on the in-tree firmware instead of the loaded
firmware. It's a bit suboptimal but doesn't matter much right now
because we're about to remove the special cases for the in-tree version
anyway.

All new crypto interfaces should go into individual files as much

The base field in ahash_tfm appears to have been cut-n-pasted from
ablkcipher. It isn't needed here at all. Similarly, the info field
in ahash_request also appears to have originated from its cipher
counter-part and is vestigial.

The digest size check on hash algorithms is incorrect. It's
perfectly valid for hash algorithms to have a digest length
longer than their block size. For example crc32c has a block
size of 1 and a digest size of 4. Rather than having it lie
about its block size, this patch fixes the checks to do what
they really should which is to bound the digest size so that
code placing the digest on the stack continue to work.
HMAC however still needs to check this as it's only defined
for such algorithms.

The name authenc(hmac(sha1-talitos),cbc(aes-talitos)) is potentially
ambiguous since it could also mean using the generic authenc template
on hmac(sha1-talitos) and cbc(aes-talitos). In general, parentheses
should be reserved for templates that spawn algorithms.
This patches changes it to the form authenc-hmac-sha1-cbc-aes-talitos.

Patch to add checking of DES3 test vectors using CBC mode. FIPS-140-2
compliance mandates that any supported mode of operation must include a self
test. This satisfies that requirement for cbc(des3_ede). The included test
vector was generated by me using openssl. Key/IV was generated with the
following command:
openssl enc -des_ede_cbc -P
input and output values were generated by repeating the string "Too many
secrets" a few times over, truncating it to 128 bytes, and encrypting it with
openssl using the aformentioned key. Tested successfully by myself

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.
