Linux 4.2-rc1

[Linus Torvalds]

It's Sunday, two weeks have passed, and the merge window is closed. I
just pushed out the tag to the git trees, and tar-balls and patches
should be mirroring out too.

I thought this release would be one of the biggest ones ever, but it
turns out that it will depend on how you count. Just counting pure
commits, it is indeed one of the bigger rc1's in recent history, but
3.10-rc1 was almost as big, and then the final 3.10 grew from that
more than most. I doubt we'll match the 3.10 release, since we have
been getting progressively better at *not* merging tons of stuff after
-rc1.

And it turns out v3.15-rc1 had more commits than 4.2-rc1 does (by a
hair), so even there this isn't the biggest rc1 ever, if you count the
number of commits.

But it's certainly up there with the best of them. It's much too big
to post the shortlog, so as usual for rc1, appended is just my
"mergelog", with the people who are credited being the people I merge
from, which is usually not necessarily at all the same thing as the
people who actually authored the code. You'll need to go look at the
details in the git tree for that.

However, if you count the size in pure number of lines changed, this
really seems to be the biggest rc we've ever had, with over a million
lines added (and about a quarter million removed). That beats the
previous champion (3.11-rc1) that was huge mainly due to Lustre being
added to the staging tree.

The reason for that huge number of lines is largely a single source:
the bulk of this by far is from the new amd gpu register description
headers. In fact, just those register descriptor headers alone are
about 41% of the entire patch. The rest of the new amdgpu driver
itself is another 8% of the total, so we're in the somewhat odd
situation where a single driver is about half of the whole rc1 in
number of lines.

Aside from that unusual anomaly, the rest looks fairly normal - mainly
drivers and architecture updates. The Renesas H8/300 architecture came
back in a newly cleaned-up form, so we have some new(ish) architecture
support, but that's tiny and the bulk is ARM (with x86 a distant
second). Interestingly, there was quite a bit of low-level x86
changes: both source code re-organization for x86 entry code and lots
of FPU handling cleanups. That's fairly unusual, with low-level x86
code being fairly stable and seldom seeing those kinds of big changes.

Outside of the "drivers and architectures", there's a fair amount of
filesystem stuff, including some fundamental changes and cleanups to
symlink handling by Al. And all the usual updates to various
filesystems, networking, crypto, tools, testing, you name it.
