config SPARSE_IRQ
	bool "Support sparse irq numbering" if MAY_HAVE_SPARSE_IRQ
	---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.

config GENERIC_IRQ_DEBUGFS
	bool "Expose irq internals in debugfs"
	depends on DEBUG_FS

	default n
	---help---

	  Exposes internal state information through debugfs. Mostly for
	  developers and debugging of hard to diagnose interrupt problems.

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

config GENERIC_IRQ_MULTI_HANDLER
	bool
	help
	  Allow to specify the low level IRQ handler at run time.
