Subject: [PATCH 00/18] crypto: Add helper functions for parallelized LRW and XTS modes

This series adds lrw_crypt() and xts_crypt() functions for cipher implementations that
can benefit from parallel cipher block operations. To make interface flexible,
caller is reponsible of allocating buffer large enough to store temporary cipher
blocks. This buffer size should be as large as size of parallel blocks processed at
once. Cryption callback is called with buffer size at maximum of parallel blocks size
and at minimum size of one block.

Series adds LRW/XTS support to serpent-sse2 and twofish-x86_64-3way, and therefore
depends on those series.

Patches 1-4: include LRW fixes/cleanups, export gf128mul table and add lrw_crypt().
Patches 5-7: add LRW support to serpent-sse2, with tcrypt tests and test vectors.
Patches 8-10: add LRW support to twofish-x86_64-3way, with tcrypt tests and test vectors.
Patches 11-12: include XTS cleanup for blocksize usage and add xts_crypt().
Patches 13-15: add XTS support to serpent-sse2, with tcrypt tests and test vectors.
Patches 16-18: add XTS support to twofish-x86_64-3way, with tcrypt tests and test vectors.

Subject: [PATCH 07/18] crypto: serpent-sse2: add lrw support

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):

Subject: [PATCH 10/18] 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

Subject: [PATCH 15/18] crypto: serpent-sse2: add xts support

Patch adds XTS support for serpent-sse2 by using xts_crypt(). Patch has been
tested with tcrypt and automated filesystem tests.

Tcrypt benchmarks results (serpent-sse2/serpent_generic speed ratios):

Intel Celeron T1600 (x86_64) (fam:6, model:15, step:13):

size xts-enc xts-dec
16B 0.98x 1.00x
64B 1.00x 1.01x
256B 2.78x 2.75x
1024B 3.30x 3.26x
8192B 3.39x 3.30x

AMD Phenom II 1055T (x86_64) (fam:16, model:10):

size xts-enc xts-dec
16B 1.05x 1.02x
64B 1.04x 1.03x
256B 2.10x 2.05x
1024B 2.34x 2.35x
8192B 2.34x 2.40x

Intel Atom N270 (i586):

size xts-enc xts-dec
16B 0.95x 0.96x
64B 1.53x 1.50x
256B 1.72x 1.75x
1024B 1.88x 1.87x
8192B 1.86x 1.83x

Subject: [PATCH 18/18] crypto: twofish-x86_64-3way: add xts support

Patch adds XTS support for twofish-x86_64-3way by using xts_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 xts-enc xts-dec
16B 0.98x 1.00x
64B 1.14x 1.15x
256B 1.23x 1.25x
1024B 1.26x 1.29x
8192B 1.28x 1.30x

AMD Phenom II 1055T (fam:16, model:10):

size xts-enc xts-dec
16B 1.03x 1.03x
64B 1.13x 1.16x
256B 1.20x 1.20x
1024B 1.22x 1.22x
8192B 1.22x 1.21x

All applied except for the serpent patches. Please resend those
after you've fixed up the previous serpent patches.

I've also merged your later fixes into these.
