Kernel prepatch 4.11-rc1

The first 4.11 kernel prepatch is out, andthe merge window is closed for this development cycle. "This lookslike a fairly regular release. It's on the smallish side, but mainly justcompared to 4.9 and 4.10 - so it's not really _unusually_ small (in recentkernels, 4.1, 4.3, 4.5, 4.7 and now 4.11 all had about the same number ofcommits in the merge window)." There were 10,960 non-merge commitspulled in the end, so it's definitely not unusually small.
