395 This enables support for sparse irqs. This is useful for distro
396 kernels that want to define a high CONFIG_NR_CPUS value but still
397 want to have low kernel memory footprint on smaller machines.

399 ( Sparse IRQs can also be beneficial on NUMA boxes, as they spread
400 out the irq_desc[] array in a more NUMA-friendly way. )
