2022-06-15	arch/*: Disable softirq stacks on PREEMPT_RT.	Sebastian Andrzej Siewior	1	-1/+1
	PREEMPT_RT preempts softirqs and the current implementation avoids do_softirq_own_stack() and only uses __do_softirq(). Disable the unused softirqs stacks on PREEMPT_RT to save some memory and ensure that do_softirq_own_stack() is not used bwcause it is not expected.

2021-02-11	softirq: Move do_softirq_own_stack() to generic asm header	Thomas Gleixner	1	-0/+14
	To avoid include recursion hell move the do_softirq_own_stack() related content into a generic asm header and include it from all places in arch/ which need the prototype. This allows architectures to provide an inline implementation of do_softirq_own_stack() without introducing a lot of #ifdeffery all over the place.
