Linux 4.14 rc2

I'm back to my usual Sunday release schedule, and rc2 is out there in
all the normal places.

This was a fairly usual rc2, with a very quiet beginning of the week,
and then most changes came in on Friday afternoon and Saturday (with
the last few ones showing up Sunday morning).

Normally I tend to dislike how that pushes most of my work into the
weekend, but this time I took advantage of it, spending the quiet part
of last week diving instead.

Anyway, the only unusual thing worth noting here is that the security
subsystem pull request that came in during the merge window got
rejected due to problems, and so rc2 ends up with most of that
security pull having been merged in independent pieces instead.

As a result, about 30% of the rc2 patches are actually things that
technically came in during the merge window, but were delayed into rc2
due to that issue.

Other than that, it's the usual mix of random stuff. Drivers
(networking, rdma and gpu stand out), architecture fixes (x86, mips,
s390, parisc, powerpc, arm), some filesystem things, generic
networking and Documentation. And the random smattering everywhere.

Nothing stands out, although hopefully we've gotten over all the x86
ASID issues. Knock wood.

Shortlog appended as a rough overview of the details.

Go test it,
