From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
v4.19.255-rt114-rc1 stable review patch. If anyone has any objections, please let me know.
-----------
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.
