I have committed patches 7 (generic code, applied with Keir's ACK) and
patches 8-24. However I stopped before applying #25 "arm: makefiles"
because the full series failed to build with:

domain_pirq_to_irq has been in the tree for quite some time so I guess
something has changed wrt implicit #includes? Can you fixup and resend
the fix plus the last three patches please.

Thanks,
Ian.
