Linux 4.6 rc7

So here's rc7, because while things were really quiet there for a
while, it nefer got *so* quiet that I would decide that there's no
point to making the traditional last rc.  But this is it, unless
something surprising happens..

There's nothing particularly odd in here, and the appended shortlog is
small enough to skim and get an overview of the details from. It's
mostly small driver fixes and some even smaller arch updates. Add some
networking, a couple of core fs and kernel fixes, and that's pretty
much it.

Nothing particularly scary, and the more people who test this out, the
more confident we can be that the final 4.6 is all good. So please
take a moment to try it out,
