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. ) | ||
