Without this I can't enable PCI_MSI_IRQ_DOMAIN, which as far as I can tell only depends on generic functionality provided by msi.h. PCI_MSI_IRQ_DOMAIN has historically had a whitelist of supported architectures, but that list is getting long enough that it's cleaner to just enable it everywhere. This builds with an s390 defconfig, but I have no access to s390 and therefor can't even boot test it.
