41 ---help---
42
43 Sparse irq numbering is useful for distro kernels that want
44 to define a high CONFIG_NR_CPUS value but still want to have
45 low kernel memory footprint on smaller machines.
46
47 ( Sparse irqs can also be beneficial on NUMA boxes, as they spread
48 out the interrupt descriptors in a more NUMA-friendly way. )

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