tools: add a kernel-chktaint to tools/debugging 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.

docs: Update documentation to reflect what TAINT_CPU_OUT_OF_SPEC means 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.

tools: Add new "test" taint to kernel-chktaint Commit c272612cb4a2 ("kunit: Taint the kernel when KUnit tests are run") added a new taint flag for when in-kernel tests run. This commit adds recognition of this new flag in kernel-chktaint. With this change the correct reason will be reported if the kernel is tainted because of a test run.
