+       ---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.
