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.
