- depends on HAVE_SPARSE_IRQ
- ---help---
- Sparse irq numbering 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 interrupt descriptors in a more NUMA-friendly way. )
- If you don't know what to do here, say N.
