Dear RT Folks,

I'm pleased to announce the 3.14.43-rt42 stable release.


This release is just an update to the new stable 3.14.43 version
and no RT specific changes have been made.


You can get this release via the git tree at:

  git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

This kernel doesn't compile with CONFIG_NO_HZ_FULL:

kernel/time/tick-sched.c: In function ‘can_stop_full_tick’:
kernel/time/tick-sched.c:183:2: error: implicit declaration of
function ‘arch_irq_work_has_interrupt’
[-Werror=implicit-function-declaration]
  if (!arch_irq_work_has_interrupt()) {
  ^
  CC      mm/pgtable-generic.o

make[2]: *** [kernel/time/tick-sched.o] Error 1
scripts/Makefile.build:455: recipe for target 'kernel/time' failed
make[1]: *** [kernel/time] Error 2


arch_irq_work_has_interrupt wasn't introduced until 3.17-rc5 with
commit c5c38ef3d70377dc504a6a3f611a3ec814bc757b.

Patch 0353-kernel-irq_work-fix-no_hz-deadlock.patch breaks the build.

Thanks for letting me know. I need to work on the stable releases again
soon. If not this week, I'll do it first thing next week.
