From: Zhiwu Song <[email protected]> irqchip will reject the affinity set to CPUs which is not online yet. but in the CPU1 wakeup stage, OS only sets CPU1 to be online after local timer is set, so that causes the irq_set_affinity not work. this patch moves to irq_force_affinity() for the low level boot stage.
