Excellent, thanks.

There is one remaining issue which I think would be really nice to 
have(TM), and that's Steven's Ack for the whole thing :)

For the livepatching part, I don't think we are quite there yet (so maybe 
it'll miss the upcoming merge window anyway).

My primary worry there is what Torsten pointed out, i.e. functions with 
either varargs or more than 8 args needing special care.

Also, I'd like to have this positively reviewed by at least one more 
livepatching maintainer (I am currently looking into it myself, but my 
understanding of powerpc arch is rather low, so the more eyes, the 
better).

Thanks!
