14	  masking.

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.

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.
