*	crypto: twofish - add AVX2/x86_64 assembler implementation of twofish cipher	Jussi Kivilinna	2013-04-25	1	-0/+180
	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.
