.. and with confirmation from Michael and Mark (and the analysis from Uros on the fallback code), I've applied this to my tree.
NOTE!
I have *not* applied the second patch with the x86-32 change to enable this on 32-bit with CMPXCHG8B enabled. I think that's independent, and will leave it up to the x86 maintainers. Plus I think the patch should be simplified.
