| |
We have a test that looks for invalid pairings of certain athlon/durons that weren't designed for SMP, and taint accordingly (with 'S') if we find such a configuration. However, this test shouldn't fire if there's only a single CPU present. It's perfectly valid for an SMP kernel to boot on UP hardware for example.
