Is this already a known > issue (possibly already fixed), or should I investigate? Seems like something is selecting GENERIC_MSI_IRQ_DOMAIN on a system that doesn't implement the required bits. It may be that we need to implement something like HAS_GENERIC_MSI_IRQ_DOMAIN, and make GENERIC_MSI_IRQ_DOMAIN conditional on that. Or just whitelist the architectures that do implement this. Any chance you could have a closer look?
