crypto: twofish-x86_64-3way - add lrw support
Patch adds LRW support for twofish-x86_64-3way by using lrw_crypt(). Patch has
been tested with tcrypt and automated filesystem tests.
Tcrypt benchmarks results (twofish-3way/twofish-asm speed ratios):
Intel Celeron T1600 (fam:6, model:15, step:13):
size lrw-enc lrw-dec
16B 0.99x 1.00x
64B 1.17x 1.17x
256B 1.26x 1.27x
1024B 1.30x 1.31x
8192B 1.31x 1.32x
AMD Phenom II 1055T (fam:16, model:10):
size lrw-enc lrw-dec
16B 1.06x 1.01x
64B 1.08x 1.14x
