Dear RT folks!

I'm pleased to announce the v6.1.12-rt7 patch set.

Changes since v6.1.12-rt6:

- Always wake the ktimers thread once the hrtimer softirq is raised.
If the softirq is running then the wake of the thread will be
delayed until the next jiffy tick. Patch by Junxiao Chang.

Known issues
None.

The delta patch against v6.1.12-rt6 is appended below and can be found here:

https://cdn.kernel.org/pub/linux/kernel/projects/rt/6.1/incr/patch-6.1.12-rt6-rt7.patch.xz
