The Kconfig and Makefile were overlooked, add those in now to improve odds of building. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

+comment "Interrupt controller options"
+
+config INTC_USERIMASK
+ bool "Userspace interrupt masking support"
+ depends on ARCH_SHMOBILE || (SUPERH && CPU_SH4A)
+ 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.
