| ---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. |
