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.

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.

This will create a debugfs entry for showing the relationship
|

between system IRQs and the per-controller id tables.
