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 256B 1.19x 1.20x 1024B 1.21x 1.22x 8192B 1.23x 1.24x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
