Linux 4.11 rc1

So two weeks have passed, the merge window is over, and 4.11-rc1 has
been tagged and pushed out.

This looks like a fairly regular release. It's on the smallish side,
but mainly just compared to 4.9 and 4.10 - so it's not really
_unusually_ small (in recent kernels, 4.1, 4.3, 4.5, 4.7 and now 4.11
all had about the same number of commits in the merge window).
