Dear RT folks!

I'm pleased to announce the v4.9.13-rt12 patch set.

Changes since v4.9.13-rt11:

- hrtimer_cancel() may not cancel a timer which is currently running
in the softirq context. Reported by Alexander Gerasiov.

Known issues
- CPU hotplug got a little better but can deadlock.

The delta patch against v4.9.13-rt11 is appended below and can be found here:
