Please use an email client that does proper quoting - I cannot see what
you are replying to. Or at least annotate your answers so that I can
spot them.

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,
