 * @domain: domain owning the interrupt range

 * @irq_base: beginning of linux IRQ range

 * @hwirq_base: beginning of hardware IRQ range

 * @count: Number of interrupts to map

 *

 * This routine is used for allocating and mapping a range of hardware

 * irqs to linux irqs where the linux irq numbers are at pre-defined

 * locations. For use by controllers that already have static mappings

 * to insert in to the domain.

 *

 * 0 is returned upon success, while any failure to establish a static

 * mapping is treated as an error.
