We are pleased to announce the next update to our new preempt-rt series.

[ I skipped -rt3 as it failed in testing ]

- update to the ONESHOT irq infrastructure scheduled for mainline

- scheduling while atomic fix in tty_ldisc

The know problems (PSeries / ARM highmem) still persist and we have a new one which is related to cgroup memcontrol. The latter one is easy to fix but will have to wait for the next release.
