Patch adds LRW support for serpent-sse2 by using lrw_crypt(). Patch has been tested with tcrypt and automated filesystem tests. Tcrypt benchmarks results (serpent-sse2/serpent_generic speed ratios): Benchmark results with tcrypt: Intel Celeron T1600 (x86_64) (fam:6, model:15, step:13): size lrw-enc lrw-dec 16B 1.00x 0.96x 64B 1.01x 1.01x 256B 3.01x 2.97x 1024B 3.39x 3.33x 8192B 3.35x 3.33x AMD Phenom II 1055T (x86_64) (fam:16, model:10): size lrw-enc lrw-dec 16B 0.98x 1.03x 64B 1.01x 1.04x 256B 2.10x 2.14x 1024B 2.28x 2.33x 8192B 2.30x 2.33x Intel Atom N270 (i586): size lrw-enc lrw-dec 16B 0.97x 0.97x 64B 1.47x 1.50x 256B 1.72x 1.69x 1024B 1.88x 1.81x 8192B 1.84x 1.79x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
