[PATCH] arch/*: Disable softirq stacks on PREEMPT_RT.

2022-06-14 Thread Sebastian Andrzej Siewior
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 safe some memory and ensure that do_softirq_own_stack() is not used bwcause it is not expected. Signed-off-by: Sebastian Andr
