Kernel prepatch 4.0-rc1

Linus has closed the merge window for this release and released 4.0-rc1 - meaning, of course, that the currentplan is to call the release "4.0". "But nobody shouldnotice. Because moving to 4.0 does *not* mean that we somehow changed whatpeople see. It's all just more of the same, just with smaller numbers sothat I can do releases without having to take off my socks again."The codename has also changed to "Hurr durr I'ma sheep."
