Linux 4.8 rc8

So as already mentioned last week (and hinted at as a possibility),
here's rc8. Things actually did start to calm down this week, but I
didn't get the feeling that there was no point in doing one final rc,
so here we are. I expect the final 4.8 release next weekend, unless
something really unexpected comes up.

There's a few straggling entries on Thorsten's regression list, but
nothing that makes me go "we need to hold off 4.8". And things realy
were pretty quiet, with just mostly random small fixes. See the
shortlog below, but it's small things all over: mostly drivers, with
some arch and crypto, and small MM and filesystem fixes. And a
smattering of networking.
