- This enables support for sparse irqs. This is useful in general
- as most CPUs have a fairly sparse array of IRQ vectors, which
- the irq_desc then maps directly on to. Systems with a high
- number of off-chip IRQs will want to treat this as
- experimental until they have been independently verified.
