Dear RT folks!

I'm pleased to announce the v4.14.24-rt19 patch set.

Changes since v4.14.24-rt18:

- Some adjtimex related code has been moved to a helper thread after
it has been claimed that it is called from hard interrupt context.
I was not able to find that hard interrupt context and now that
change is reverted.

Known issues
- A warning triggered in "rcu_note_context_switch" originated from
SyS_timer_gettime(). The issue was always there, it is now
visible. Reported by Grygorii Strashko and Daniel Wagner.

The delta patch against v4.14.24-rt18 is appended below and can be found here:
