8cb51ba8e0 crypto: crc32c - Use Intel CRC32 instruction
From NHM processor onward, Intel processors can support hardware accelerated
CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set.
The patch detects the availability of the feature, and chooses the most proper
way to calculate CRC32c checksum.
Byte code instructions are used for compiler compatibility.
No MMX / XMM registers is involved in the implementation.

9a7dafbba4 [CRYPTO] salsa20: Add x86-64 assembly version
This is the x86-64 version of the Salsa20 stream cipher algorithm. The
original assembly code came from
<http://cr.yp.to/snuffle/salsa20/amd64-3/salsa20.s>. It has been
reformatted for clarity.

974e4b752e [CRYPTO] salsa20_i586: Salsa20 stream cipher algorithm (i586 version)
This patch contains the salsa20-i586 implementation. The original
assembly code came from
<http://cr.yp.to/snuffle/salsa20/x86-pm/salsa20.s>. I have reformatted
it (added indents) so that it matches the other algorithms in
arch/x86/crypto.

06e1a8f050 [CRYPTO] aes-asm: Merge common glue code
32 bit and 64 bit glue code is using (now) the same
piece code. This patch unifies them.
