  43
  44           Sparse irq numbering is useful for distro kernels that want
  45           to define a high CONFIG_NR_CPUS value but still want to have
  46           low kernel memory footprint on smaller machines.
  47
  48           ( Sparse irqs can also be beneficial on NUMA boxes, as they spread
  49             out the interrupt descriptors in a more NUMA-friendly way. )

  51           If you don't know what to do here, say N.
