Things seem to be finally starting to calm down for 4.14.
We've certainly had smaller rc5's, but we've had bigger ones too, and this week finally felt fairly normal in a release that has up until now felt a bit messier than it perhaps should have been.
So assuming this trend holds, we're all good. Knock wood.
So what do we have here? A little bit of everything, but what might be most noticeable is some more fixes for the whole new x86 TLB handling due to the ASID changes that came in this release. Some of the lazy TLB handling changes caused problems on a few AMD chips with particular settings, because it was all a little bit *too* lazy in flushing the TLB. Even when TLB entries aren't used (and will be flushed before any possible use), the TLB may be speculatively filled, and that can cause problems if we've already free'd the page tables that the speculative fill ends up looking up.
The other thing perhaps worth mentioning is how much random fuzzing people are doing, and it's finding things. We've always done fuzzing (who remembers the old "crashme" program that just generated random code and jumped to it? We used to do that quite actively very early on), but people have been doing some nice targeted fuzzing of driver subsystems etc, and there's been various fixes (not just this last week either) coming out of those efforts. Very nice to see.
Anyway, rc5 is out, and things look normal. We've got arch updates (mostly x86and poweerpc, but some mips), drivers (gpu, networking, usb, sound, misc), some core kernel (lockdep fixes, networking, mm) and some tooling (perf, selftests).
