The result can be found at git://git.kiszka.org/qemu-kvm.git kvm-irqchip-merge The integration of the upstream irqchip patches was, as expected, not that hard. But the merge of my earlier refactorings, the backend/frontend split-up caused some efforts. I'm not sure what to do with that branch. We could either try to merge it before pulling in an upstream version that includes the new irqchips. But that won't work without manual conflict resolution as well. Or the branch can serve as a reference for re-doing a merge later on.
