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

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

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

  39           If in doubt, say N.
