Jussi Kivilinna	cf1521a1a5	crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipher ... Patch adds AVX2/x86-64 implementation of Twofish cipher, requiring 16 parallel blocks for input (256 bytes). Table look-ups are performed using vpgatherdd instruction directly from vector registers and thus should be faster than earlier implementations. Implementation also uses 256-bit wide YMM registers, which should give additional speed up compared to the AVX implementation.

Jussi Kivilinna	58990986f1	crypto: x86/glue_helper - use le128 instead of u128 for CTR mode ... 'u128' currently used for CTR mode is on little-endian 'long long' swapped and would require extra swap operations by SSE/AVX code. Use of le128 instead of u128 allows IV calculations to be done with vector registers easier.

Jussi Kivilinna	a7378d4e55	crypto: twofish-avx - remove duplicated glue code and use shared glue code from glue_helper ... Now that shared glue code is available, convert twofish-avx to use it.
