Peter Zijlstra 6816509065 sched/core: Allow try_invoke_on_locked_down_task() with irqs disabled ... commit 1b7af29554 upstream. The try_invoke_on_locked_down_task() function currently requires that interrupts be enabled, but it is called with interrupts disabled from rcu_print_task_stall(), resulting in an "IRQs not enabled as expected" diagnostic. This commit therefore updates try_invoke_on_locked_down_task() to use raw_spin_lock_irqsave() instead of raw_spin_lock_irq(), thus allowing use from either context.
