== Highlights ==

* Lots of work for KDB FIQ/NMI debugger, sent out v5, v6 and v7. Switched NMI console driver to tty_port infrastructure, discussed the ways to handle serial interrupts quiescing, made magic sequence configurable. TTY patches got Alan Cox's ack.

* Looked into timer slack support for cgroups. While it's indeed somewhat close to deferrable timers, it's still not exactly what we need. Timer slack let us group wakeups, but there is still no way to tell that the timer/poll/select itself should not cause wakeups. As for deferrable timers, there are still no comments.

* Looked into ideas on early OOM detection from the userland. There are a lot of inspirational thoughts on measuring memory stress levels, and I definitely need to perform some tests. I'll prepare a detailed answer to the ideas, but the most interesting part is that the ideas are based on vmstat monitoring, which is important: if we're going to use vmstat, we'll eventually get beaten by vmstat downsides: slow/expensive updates (so the latency if the pre-OOM detection would be equal to vmstat_update_time). And for Android low memory killer use case, pre-OOM condition is important, but not the main problem: the main "problem" is to monitor memory level when there is no stress at all (but deferrable timers would solve this).

* Rebased and applied pstore/ftrace debugfs rework, this is now in linux-next. Also reviewed/fixed FDT support for pstore, by Bryan Freed @ Chromium.org.
