Linux 4.3 rc4

You all know the drill by now. It's Sunday, and there is a new release
candidate out there.

Things look fairly normal. We have noticeably fewer commits than rc3
(which was fairly big), and I don't see anything unusually alarming.
The statistics look pretty normal too: just under half of the patch is
drivers (drm continues to be noticeable, but there's infiniband, mmc,
input layer etc). About a quarter is arch updates (m68k, MIPS, x86)
and the final quarter is solidly "misc" (doc updates, tools, scripts,
scheduler, mm..).

The appended shortlog gives a flavor of the details.
