Subject: [ANNOUNCE] v4.14.24-rt19

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:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.14/incr/patch-4.14.24-rt18-rt19.patch.xz
