| 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. |

| 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. |
