This patch makes IRQ_DOMAIN usable on MIPS.  It uses an ugly workaround

registration to the irq controller drivers.  The workaround will be
removed in Linux v3.6


Looking good, Ack.

Is there any good example for the changes that need to be done to
irq controller drivers?

Well it only affects things that have USE_OF, so most mips things willnot need to do anything as they don't USE_OF.

But for those that do USE_OF, you have to call one or more of theirq_domain_add_*() functions.

Slightly off topic: My OCTEON patch set tries to do this, but hasn'tmet with quite as much enthusiasm as I would have liked...
