crypto: camellia - add AES-NI/AVX/x86_64 assembler implementation of camellia cipher
This patch adds AES-NI/AVX/x86_64 assembler implementation of Camellia block cipher. Implementation process data in sixteen block chunks, which are byte-sliced and AES SubBytes is reused for Camellia s-box with help of pre- and post-filtering. Patch has been tested with tcrypt and automated filesystem tests. tcrypt test results: Intel Core i5-2450M: camellia-aesni-avx vs camellia-asm-x86_64-2way: 128bit key: (lrw:256bit) (xts:256bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.98x 0.96x 0.99x 0.96x 0.96x 0.95x 0.95x 0.94x 0.97x 0.98x 64B 0.99x 0.98x 1.00x 0.98x 0.98x 0.99x 0.98x 0.93x 0.99x 0.98x 256B 2.28x 2.28x 1.01x 2.29x 2.25x 2.24x 1.96x 1.97x 1.91x 1.90x 1024B 2.57x 2.56x 1.00x 2.57x 2.51x 2.53x 2.19x 2.17x 2.19x 2.22x 8192B 2.49x 2.49x 1.00x 2.53x 2.48x 2.49x 2.17x 2.17x 2.22x 2.22x 256bit key: (lrw:384bit) (xts:512bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.97x 0.98x 0.99x 0.97x 0.97x 0.96x 0.97x 0.98x 0.98x 0.99x 64B 1.00x 1.00x 1.01x 0.99x 0.98x 0.99x 0.99x 0.99x 0.99x 0.99x 256B 2.37x 2.37x 1.01x 2.39x 2.35x 2.33x 2.10x 2.11x 1.99x 2.02x 1024B 2.58x 2.60x 1.00x 2.58x 2.56x 2.56x 2.28x 2.29x 2.28x 2.29x 8192B 2.50x 2.52x 1.00x 2.56x 2.51x 2.51x 2.24x 2.25x 2.26x 2.29x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Acked-by: David S.
