irq_wake_thread	q_wake_thread - wake the irq thread for the action identified by dev_id@irq: Interrupt line@dev_id: Device identity for which the thread should be woken
setup_irq	注册中断
remove_irq	move_irq - free an interrupt@irq: Interrupt line to free@act: irqaction for the interrupt* Used to remove interrupts statically setup by the early boot process.
free_irq	_irq - free an interrupt allocated with request_irq@irq: Interrupt line to free@dev_id: Device identity to free* Remove an interrupt handler

request_threaded_irq	注册中断线程
request_nmi	quest_nmi - allocate an interrupt line for NMI delivery@irq: Interrupt line to allocate@handler: Function to be called when the IRQ occurs
remove_percpu_irq	move_percpu_irq - free a per-cpu interrupt@irq: Interrupt line to free@act: irqaction for the interrupt* Used to remove interrupts statically setup by the early boot process.
free_percpu_irq	_percpu_irq - free an interrupt allocated with request_percpu_irq@irq: Interrupt line to free@dev_id: Device identity to free* Remove a percpu interrupt handler. The handler is removed, but* the interrupt line is not disabled. This must be done on each
