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. )

51 If you don't know what to do here, say N.
