 13           This enables support for hardware-assisted userspace hardirq
 14           masking.
 15 
 16           SH-4A and newer interrupt blocks all support a special shadowed
 17           page with all non-masking registers obscured when mapped in to
 18           userspace. This is primarily for use by userspace device
 19           drivers that are using special priority levels.

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

 37         help
 38           This will create a debugfs entry for showing the relationship
 39           between system IRQs and the per-controller id tables.

 41           If in doubt, say N.
