6 | * Special hack: we have to be careful, because no indirections are allowed here, |
7 | * and paravirt_ops is a kind of one. As it will only run in baremetal anyway, | |
8 | * we just keep it from happening. (This list needs to be extended when new | |
9 | * paravirt and debugging variants are added.) | |
