From 547f574fd9d5e3925d47fd44decbf6ab6df94b0e Mon Sep 17 00:00:00 2001 From: Mathieu Chouquet-Stringer Date: Wed, 2 Dec 2020 16:32:43 +0100 Subject: 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.
