Hi Anton,

These days I'm the one handling pdx86 patches. I took this into the
review-ilpo-fixes branch and reinstated Hans' ack.

My experience is that long delays are nothing unusual when interacting 
with Dimitry so don't get discouraged by that when it comes to the
rest of v2 content. Once Dimitry has okay'ed the input side change, please 
resubmit the rest.
