Kees Cook 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:

Jussi Kivilinna cfe82d4f45 crypto: sha512_ssse3 - fix byte count to bit count conversion
Byte-to-bit-count computation is only partly converted to big-endian and is
mixing in CPU-endian values. Problem was noticed by sparce with warning:

  CHECK   arch/x86/crypto/sha512_ssse3_glue.c

Jussi Kivilinna 340991e30c crypto: sha512_ssse3 - add sha384 support
Add sha384 implementation to sha512_ssse3 module.

This also fixes sha512_ssse3 module autoloading issue when 'sha384' is used
before 'sha512'. Previously in such case, just sha512_generic was loaded and
not sha512_ssse3 (since it did not provide sha384). Now if 'sha512' was used
after 'sha384' usage, sha512_ssse3 would remain unloaded. For example, this
happens with tcrypt testing module since it tests 'sha384' before 'sha512'.

Tim Chen 87de4579f9 crypto: sha512 - Create module providing optimized SHA512 routines using SSSE3, AVX or AVX2 instructions.
We added glue code and config options to create crypto
module that uses SSE/AVX/AVX2 optimized SHA512 x86_64 assembly routines.
