Subject: genirq: update irq_set_irqchip_state documentation
From: Josh Cartwright <joshc@ni.com>
Date: Thu Feb 11 11:54:00 2016 -0600
From: Josh Cartwright <joshc@ni.com>
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.
