Michael Ellerman 34f7f79827 selftests/powerpc: Add test of mitigation patching ... We recently discovered some of our mitigation patching was not safe against other CPUs running concurrently. Add a test which enable/disables all mitigations in a tight loop while also running some stress load. On an unpatched system this almost always leads to an oops and panic/reboot, but we also check if the kernel becomes tainted in case we have a non-fatal oops.
