    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,
