| 41 | depends on HAVE_SPARSE_IRQ |
| 42 | ---help--- |
| 43 | |
| 44 | Sparse irq numbering is useful for distro kernels that want |
| 45 | to define a high CONFIG_NR_CPUS value but still want to have |
| 46 | low kernel memory footprint on smaller machines. |
| 47 | |
| 48 | ( Sparse irqs can also be beneficial on NUMA boxes, as they spread |
| 49 | out the interrupt descriptors in a more NUMA-friendly way. ) |
| 50 | |
| 51 | If you don't know what to do here, say N. |
