patch

It looks like the amd64 futex operations are simply broken with SMAP enabled? 
I'm not sure how this ever worked.  Please try the attached patch to confirm, I
did not test it.

I'm not sure if your patch is correct either but indeed it would be preferable
to implement these ops without custom asm primitives.
