SubjectLinux 4.9-rc2
I'm back on my usual Sunday afternoon release schedule, and 4.9-rc2 is out.

My favorite new feature that I called out in the rc1 announcement (the
virtually mapped stacks) is possibly implicated in some crashes that
Dave Jones has been trying to figure out, so if you want to be helpful
and try to see if you can give more data, please make sure to enable
CONFIG_VMAP_STACK.

.. and on the other hand, if you want to just not have to worry about
_that_ particular issue, disable the virtually mapped stacks it for
now, but please do help test.

Because 4.9 is obviously shaping up to be a big release (I haven't
done the actual stats yet, but I think it's the biggest in number of
commits we've ever had), and I think Greg is also planning on making
it an LTS release. The two may be related, with people pushing to get
their stuff ready. Regardless, the more people who help test, and the
earlier in the rc series those people start testing, the better off
we'll be. Hint hint.

Ok, enough about that. rc2 itself isn't huge, but that's a fairly
common pattern: either people just take a breather after the merge
window, or it simply takes a while for the fallout of new code to be
found, so rc2 is usually a fairly small rc.

But we have stuff pretty much all over the map: drivers dominate (gpu
drivers stand out, but there's ipmi, clocksource, mmc, pinctrl, HID,
scsi, nvme .. you name it). Add some architecture updates (x86 and
arm64) and a few filesystems (ext4, nfs, ceph, f2fs), and some VM
cleanups and one big fix, and you've covered most of it.

The appended shortlog gives the details, and for even more detail you
can always go to the git tree itself.
