Subject: lib/raid6: SSSE3 optimized recovery functions v2

Hi Folks,

The following patchset adds SSSE3 optimized recovery
functions to RAID6.

This version differs from version 1, in that:
        0) cpu_has_ssse3 is moved to within the #ifdef block
	1) the functions are moved into their own file, recov_ssse3.c
	2) a superfluous memory load is removed from raid6_2data_recov_ssse3

A technical description of the algorithm can be found
at http://www.kernel.org/pub/linux/kernel/people/hpa/raid6.pdf

Thanks.
