Subject: [ANNOUNCE] v4.14.29-rt25

Dear RT folks!

I'm pleased to announce the v4.14.29-rt25 patch set. 

Changes since v4.14.29-rt24:

  - There are checks for disabled interrupts in the target code which do
    not work on RT. Reported by Arnaldo Carvalho de Melo.

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 v4.14.29-rt24 is appended below and can be found here:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/4.14/incr/patch-4.14.29-rt24-rt25.patch.xz
