SSE2 optimizations for Serpent in XTS mode.

[netguru <netguru@xxxxxxx>]

Hello everyone,

Recently i was looking at libbotan's changelog, and i found that using
SSE2 parallell processing for serpent was quite a speed improvement.

Same  in  the neat little DiskCryptor program, wich uses the same kind
of optimization for serpent in XTS mode.

There  is  no  point in using SSE2 in CBC and other modes wich require
sequential  processing, but in XTS's (and a few other modes) case this
really makes a big difference.

Is  there anyone capable and or willing to implement this in the linux
kernel  ?  Maybe  in  the  form of a patch or a module ? Dont have the
sources  from  the  diskcryptor implementation, but libbotan does sure
have one as well.

Regards...
