I'd rather not until I've moved my cubox kernel tree to v3.7 (when it's
out.) Keeping stuff straight between that tree and mainline is far from
easy - I'm having to maintain two independent patches for each change,
one against each kernel tree, one gets tested (the one in the cubox tree)
the other (against mainline) does not.
