Kernel prepatch 4.12-rc6

The 4.12-rc6 kernel prepatch is out fortesting. "The good news is that rc6 is smaller than rc5 was, and I think we'reback on track and rc5 really was big just due to random timing. We'llsee. Next weekend when I'm back home and do rc7, I'll see how I feelabout things. I'm still hopeful that this would be a normal releasecycle where rc7 is the last rc."
