Yeah, Joerg just sent me a diff on how to intercept #DF. I'll add a

3.16-rc2+ - "+" is tip/master from the last weekend with a couple of
patches to arch/x86/ from me which should be unrelated (yeah, we've
heard that before :-)).

Thanks for the suggestions, I'm going for a run now but after I get

Stay tuned.
