The generic irq Kconfig options are copied around all archs. Provide a
generic Kconfig file which can be included.

	---help---



	  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.
