Thomas Gleixner 78085d7e38 x86/speculation: Provide IBPB always command line options ... commit 55a974021e upstream Provide the possibility to enable IBPB always in combination with 'prctl' and 'seccomp'. Add the extra command line options and rework the IBPB selection to evaluate the command instead of the mode selected by the STIPB switch case.
