For an A15 guest we want to say that userspace GIC isn't permitted (ie you must use the in-kernel-irqchip). For an A9 guest you would have to use the userspace GIC, but on the other hand we don't currently actually support an A9 guest... It seems a little unfortunate to remove code that is actually working but I could certainly see the cleanliness argument for dropping it and letting anybody who wanted an A9 guest put it back later. -- PMM
