m68k: Call timer_interrupt() with interrupts disabled
[ Upstream commit 1efdd4bd254311498123a15fa0acd565f454da97 ]
Some platforms execute their timer handler with the interrupt priority
level set below 6. That means the handler could be interrupted by another
driver and this could lead to re-entry of the timer core.
Avoid this by use of local_irq_save/restore for timer interrupt dispatch.
This provides mutual exclusion around the timer interrupt flag access
which is needed later in this series for the clocksource conversion.
