| The self-test wasn't always 100% accurate for RT. We disabled a few |
| tests which failed because they had a different semantic for RT. Some |
| still reported false positives. Now the selftest locks up the system |
| during boot and it needs to be investigated… |

| Say Y here if you want the kernel to run a short self-test during |
| bootup. The self-test checks whether common types of locking bugs |
