46 depends on HAVE_SPARSE_IRQ
47 ---help---
48
49 Sparse irq numbering is useful for distro kernels that want
50 to define a high CONFIG_NR_CPUS value but still want to have
51 low kernel memory footprint on smaller machines.
52
53 ( Sparse irqs can also be beneficial on NUMA boxes, as they spread
54 out the interrupt descriptors in a more NUMA-friendly way. )
55
56 If you don't know what to do here, say N.
