Did you at least make an attempt to find other examples of where
we dynamically determine the log level to be used for a message?
I would assume that if you did, you'd have come to
printk(XENLOG_GUEST "%s" VTDPREFIX
" It's %s to assign %04x:%02x:%02x.%u"
" with shared RMRR at %"PRIx64" for Dom%d.\n",
relaxed ? XENLOG_WARNING : XENLOG_ERROR,
relaxed ? "risky" : "disallowed",
seg, bus, PCI_SLOT(devfn), PCI_FUNC(devfn),
rmrr->base_address, d->domain_id);
pretty naturally.
