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.
