函数名称：handle_percpu_devid_fasteoi_nmi - Per CPU local NMI handler with per cpu* dev ids*@desc: the interrupt description structure for this irq* Similar to handle_fasteoi_nmi, but handling the dev_id cookie* as a percpu pointer.

函数原型：void handle_percpu_devid_fasteoi_nmi(struct irq_desc *desc)

返回类型：void
