+Subject: [PATCH 344/351] timers: Keep interrupts disabled for TIMER_IRQSAFE
+ timer.
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=c954214601502e0896ac0b81f1222879dad55393
+
+Keep interrupts disabled across callback invocation for the
+TIMER_IRQSAFE as expected.
+This is required for the timer used by workqueue after the upcomming
+rework.
