I've held off on putting them in irqdomain/next because they are a bit more
risky than the other patches, and I want an explicit ack from Ben for patches
24 & 25.  However, that shouldn't really cause any issues since the changes
in 24 & 25 don't impact the irq_domain functionality or API.  They are just
optimizations.

Also on 25, I'm not yet convinced that breaking out the revmap functions
into ops is the right thing to do.  It actually makes the .text size quite
a bit larger.  I may very well rewrite it.
