	bool "Support sparse irq numbering"
	depends on HAVE_SPARSE_IRQ
	---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.
