This patch adds a x86_64/avx assembler implementation of the Serpent block
cipher. The implementation is very similar to the sse2 implementation and
processes eight blocks in parallel. Because of the new non-destructive three
operand syntax all move-instructions can be removed and therefore a little
performance increase is provided.
Patch has been tested with tcrypt and automated filesystem tests.
Tcrypt benchmark results:
