[ANNOUNCE] v6.2-rt3

[ANNOUNCE] v6.2-rt3

[Sebastian Andrzej Siewior]

Dear RT folks!

I'm pleased to announce the v6.2-rt3 patch set. 

Changes since v6.2-rt2:

  - 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.

  - The splats reported by Valentin Schneider have been dealt with and
    are removed from the "known issues" sections. See
      https://lore.kernel.org/all/953300ac-25fa-db8d-c270-d10559a0fa02@arm.com/

Known issues
     None.
