| 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. | |
