  • Here's a patch updating the meaning of TAINT_CPU_OUT_OF_SPEC after
    Borislav introduced changes in a7e1f67ed29f and upcoming patches in tip.

    TAINT_CPU_OUT_OF_SPEC now means a bit more what it implies as the
    flag isn't set just because of a CPU misconfiguration or mismatch.
    Historically it was for SMP kernel oops on an officially SMP incapable
    processor but now it also covers CPUs whose MSRs have been incorrectly
    poked at from userspace, drivers being used on non supported
    architectures, broken firmware, mismatched CPUs, ...

    Update documentation and script to reflect that.

  • Add a script to the tools/ directory that shows if or why the running
    kernel was tainted. The script was mostly written by Randy Dunlap; I
    enhanced the script a bit. There does not appear to be a good home for
    this script. so create tools/debugging for tools of this nature.
