                        This parameter controls the MDS mitigation. The
                        options are:
 
-                       full    - Enable MDS mitigation on vulnerable CPUs
-                       off     - Unconditionally disable MDS mitigation
+                       full       - Enable MDS mitigation on vulnerable CPUs
+                       full,nosmt - Enable MDS mitigation and disable
+                                    SMT on vulnerable CPUs
+                       off        - Unconditionally disable MDS mitigation
 
                        Not specifying this option is equivalent to
                        mds=full.
