				77	Sparse irq numbering is useful for distro kernels that want
				78	to define a high CONFIG_NR_CPUS value but still want to have
				79	low kernel memory footprint on smaller machines.

				81	( Sparse irqs can also be beneficial on NUMA boxes, as they spread
				82	out the interrupt descriptors in a more NUMA-friendly way. )
