| 14 | This enables support for hardware-assisted userspace hardirq | |
| 15 | masking. | |
| 16 | ||
| 17 | SH-4A and newer interrupt blocks all support a special shadowed | |
| 18 | page with all non-masking registers obscured when mapped in to | |
| 19 | userspace. This is primarily for use by userspace device | |
| 20 | drivers that are using special priority levels. | |

| 27 | help | |
| 28 | This enables support for IRQ auto-distribution mode on SH-X3 | |
| 29 | SMP parts. All of the balancing and CPU wakeup decisions are | |
| 30 | taken care of automatically by hardware for distributed | |
| 31 | vectors. | |

| 39 | This will create a debugfs entry for showing the relationship | |
| 40 | between system IRQs and the per-controller id tables. | |
