Uhm, the bug you are making a big deal of would have been found and 
fixed by Paulus a few hours after any such mail - and probably by me 
too as i do daily cross builds to Power.

So yes, we had a bug, but any extra linux-next hoops would not have 
prevented it: i could still have messed up by getting lured by that 
nice piece of Power7 hardware enablement patch on the last day ;-)

So the bug was my fault for being too fast-and-loose with that 
particular patch, creating a ~5-commits-hop build breakage bisection 
window on Power.

Now that i'm sufficiently chastised, can we now move on please? :)
