I've done a bunch of refactoring work on the irq_domain infrastructure. Some of these patches I've posted before, and some our brand new. The goal of this is to greatly simplify how irq_domains work. With this series, instead of there being multiple different types of irq domains, each with different mapping rules, instead there is now only one time of irq_domain that contains both kinds of map; the linear map for irqs below a certain value, and the radix tree for large & sparse irq controllers. As you can see from the following diffstat, the result is a fair bit less code. It should make it easier to understand irqdomains too.

The branch above includes both. I've tested this on ARM qemu models, but not much else. I'll test on real hardware before pushing out, but I would appreciate anybody doing additional testing, particularly on PowerPC and other non-ARM platforms.
