Ok, I've tentatively applied this irqchip/hip04.  Once I merge that
branch into irqchip/core, you can consider it a stable base to merge in
with the rest of your series.  With everyone at KS this week, I'm going
to let things cook in -next a little longer than usual.  So, it'll
probably be early next week when I merge this in to irqchip/core.

fwiw, there are still a few things I'd like to comment on in this
driver.  However, we've beat it up enough.  As long as it isn't
adversely affecting irq-gic for everyone else, let's merge it and get
the ball moving.  My comments can easily be follow-on patches.

thx,

Jason.
