	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.

2019-01-08	tools: add a kernel-chktaint to tools/debugging	Thorsten Leemhuis
	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.
