  	  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.
