So rc2 is out, and things look fairly normal.
The diff looks a bit unusual, with the tools subdirectory dominating,
with 30%+ of the whole diff. Mostly perf and test scripts.
But if you ignore that, the rest looks fairly usual. Arch updates
(s390 and x86 dominate) and drivers (networking, gpu, HID, mmc, misc)
are the bulk of it, with misc other changes all over (filesystems,
core kernel, networking, docs).
We've still got some known fallout from the merge window, but it
shouldn't affect most normal configurations, so go out and test.
