Currently several block-ciphers in arch/x86/crypto duplicate glue code for using
assembler implementations that process multiple blocks parallel. This patchset
adds shared glue_helper module for these 128bit cipher modules to use.
Downside of generalisation of glue code is slightly increased overhead. Tcrypt
test results of camellia-x86_64, twofish-x86_64-3way and serpent-sse2 (new/old
ratio, average of ecb, cbc, ctr):
camellia twofish serpent
16 bytes: 0.926x 0.945x 0.980x
64 bytes: 0.977x 0.968x 0.982x
256 bytes: 0.980x 0.984x 0.982x
1024 bytes: 0.987x 0.992x 0.985x
4096 bytes: 0.988x 0.993x 0.985x
For ciphers utilising SSE/AVX instructions, shared ablk_helper module is added
for registering async-ciphers.

Jussi Kivilinna (11):
crypto: ablk_helper - move ablk_* functions from serpent-sse2/avx glue code to shared module
crypto: twofish-avx - change to use shared ablk_* functions
crypto: aes_ni - change to use shared ablk_* functions
crypto: serpent-sse2 - prepare serpent-sse2 glue code into generic x86 glue code for 128bit block ciphers
crypto: serpent-sse2 - split generic glue code to new helper module
crypto: serpent-avx: remove duplicated glue code and use shared glue code from glue_helper
crypto: camellia-x86_64 - remove duplicated glue code and use shared glue code from glue_helper
crypto: twofish-x86_64-3way - remove duplicated glue code and use shared glue code from glue_helper
crypto: twofish-avx - remove duplicated glue code and use shared glue code from glue_helper
crypto: move arch/x86/include/asm/serpent-{sse2|avx}.h to arch/x86/include/asm/crypto/
crypto: move arch/x86/include/asm/aes.h to arch/x86/include/asm/crypto/
