				67	Sparse irq numbering is useful for distro kernels that want
				68	to define a high CONFIG_NR_CPUS value but still want to have
				69	low kernel memory footprint on smaller machines.
				70
				71	( Sparse irqs can also be beneficial on NUMA boxes, as they spread
				72	out the interrupt descriptors in a more NUMA-friendly way. )
				73
				74	If you don't know what to do here, say N.
