36 bool "Support sparse irq numbering"
37 depends on HAVE_SPARSE_IRQ
40 Sparse irq numbering is useful for distro kernels that want
41 to define a high CONFIG_NR_CPUS value but still want to have
42 low kernel memory footprint on smaller machines.
44 ( Sparse irqs can also be beneficial on NUMA boxes, as they spread
45 out the interrupt descriptors in a more NUMA-friendly way. )
