Subject: [PATCH 210/330] genirq: update irq_set_irqchip_state documentation
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.127-rt55.tar.xz

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.
