Kernel prepatch 4.12-rc7

The 4.12-rc7 kernel prepatch is out."It's fairly small, and there were no huge surprises, so if nothinguntoward happens this upcoming week, this will be the final rc. But asusual, I reserve the right to just drag things out if I end up feelinguncomfortable about things for any reason including just random gutfeelings, so we'll see."
