config INTC_USERIMASK
	bool "Userspace interrupt masking support"
	depends on (SUPERH && CPU_SH4A) || COMPILE_TEST
	help
	  This enables support for hardware-assisted userspace hardirq
	  masking.

SH-4A and newer interrupt blocks all support a special shadowed
	  page with all non-masking registers obscured when mapped in to
	  userspace. This is primarily for use by userspace device
	  drivers that are using special priority levels.

If in doubt, say N.

config INTC_BALANCING
	bool "Hardware IRQ balancing support"
	depends on SMP && SUPERH && CPU_SHX3
	help
	  This enables support for IRQ auto-distribution mode on SH-X3
	  SMP parts. All of the balancing and CPU wakeup decisions are
	  taken care of automatically by hardware for distributed
	  vectors.

If in doubt, say N.

config INTC_MAPPING_DEBUG
	bool "Expose IRQ to per-controller id mapping via debugfs"
	depends on DEBUG_FS
	help
	  This will create a debugfs entry for showing the relationship
	  between system IRQs and the per-controller id tables.

If in doubt, say N.
