try_one_irqRecovery handler for misrouted interrupts.
handle_simple_irqhandle_simple_irq - Simple and software-decoded IRQs.*@desc: the interrupt description structure for this irq* Simple interrupts are either sent from a demultiplexing interrupt* handler or come from hardware, where no interrupt hardware control
handle_level_irqhandle_level_irq - Level type irq handler*@desc: the interrupt description structure for this irq* Level type interrupts are active as long as the hardware line has* the active level
handle_fasteoi_irqhandle_fasteoi_irq - irq handler for transparent controllers*@desc: the interrupt description structure for this irq* Only a single callback will be issued to the chip: an ->eoi()* call when the interrupt has been serviced
handle_edge_irqhandle_edge_irq - edge type IRQ handler*@desc: the interrupt description structure for this irq* Interrupt occures on the falling and/or rising edge of a hardware* signal. The occurrence is latched into the irq controller hardware
