- This enables support for sparse irqs. This is useful for distro
- kernels that want to define a high CONFIG_NR_CPUS value but still
- want to have low kernel memory footprint on smaller machines.

- ( Sparse IRQs can also be beneficial on NUMA boxes, as they spread
- out the irq_desc[] array in a more NUMA-friendly way. )
