函数名称：handle_percpu_devid_irq - Per CPU local irq handler with per cpu dev ids*@desc: the interrupt description structure for this irq* Per CPU interrupts on SMP machines without locking requirements

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

返回类型：void

参数：

类型参数名称
struct irq_desc *desc
925  chip等于irq_desc_get_chip(desc)
926  action等于中断服务例程链表
927  irq等于irq_desc_get_irq(desc)
