[PATCH RT 5/9] timers: Keep interrupts disabled for TIMER_IRQSAFE timer.

[Daniel Wagner]

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

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.
