Please give me clarity on this. This has nothing to do with the version of the GIC you are using (XGene doesn't have GICv2m or v3 either). This is about reducing code duplication and having something that we can maintain. See also https://lkml.org/lkml/2015/9/20/193 for yet another example. I still plan to kill msi_controller, and I'd like to avoid more dependencies with it. MSI domains are the way to do it. Thanks, M. -- Jazz is not dead.
