[PATCH] genirq: update irq_set_irqchip_state documentation

From: Sebastian Andrzej Siewior
Date: Fri Sep 17 2021 - 06:31:08 EST


From: Josh Cartwright <joshc@xxxxxx>

On -rt kernels, the use of migrate_disable()/migrate_enable() is
sufficient to guarantee a task isn't moved to another CPU. Update the
irq_set_irqchip_state() documentation to reflect this.
