Hi Folks,

The following patch adds an AVX implementation of the RAID5 xor checksumming
functions.

Based on xor_speed, the AVX implementation appears to be ~32% faster than the
SSE implementation on my i7 2600:

        generic_sse: 15088.000 MB/sec
	avx: 19936.000 MB/sec

Thanks.

I think this (and the SSSE3 patches for RAID-6) should go in via the
RAID tree.  Neil, do you agree?

I'm happy to take the SSSE3 RAID-6 patches as they only affect lib/raid6, but
I felt that this one - being purely in arch/x86 - should probably go via the
x86 tree.
However I'm flexible and if you (collectively) are happy with these patches
going in through my tree, I'll do that.

Thanks,
NeilBrown
