Subject: [PATCH 210/354] genirq: update irq_set_irqchip_state documentation
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=f9d2bf702086e94b24cbd77e8d8319a789331cdd
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.
