kstat_irqs_cpu | kstat_irqs_cpu - Get the statistics for an interrupt on a cpu*@irq: The interrupt number*@cpu: The cpu number* Returns the sum of interrupt counts on @cpu since boot for*@irq. The caller must ensure that the interrupt is not removed* concurrently. |
kstat_irqs | kstat_irqs - Get the statistics for an interrupt*@irq: The interrupt number* Returns the sum of interrupt counts on all cpus since boot for*@irq. The caller must ensure that the interrupt is not removed* concurrently. |
synchronize_hardirq | synchronize_hardirq - wait for pending hard IRQ handlers (on other CPUs)*@irq: interrupt number to wait for* This function waits for any pending hard IRQ handlers for this* interrupt to complete before returning |
synchronize_irq | synchronize_irq - wait for pending IRQ handlers (on other CPUs)*@irq: interrupt number to wait for* This function waits for any pending IRQ handlers for this interrupt* to complete before returning. If you use this function while |

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 |
free_percpu_nmi | |
setup_percpu_irq | setup_percpu_irq - setup a per-cpu interrupt*@irq: Interrupt line to setup*@act: irqaction for the interrupt* Used to statically setup per-cpu interrupts in the early boot process. |

irq_cpu_online | q_cpu_online - Invoke all irq_cpu_online functions.* Iterate through all irqs and invoke the chip.irq_cpu_online()* for each. |
irq_cpu_offline | q_cpu_offline - Invoke all irq_cpu_offline functions.* Iterate through all irqs and invoke the chip.irq_cpu_offline()* for each. |
