+The preempt-rt patches no longer use CONFIG_PREEMPT_RT in
+the 3.4 (and newer) versions.  So even though LTSI doesn't
+include RT, having this define present can lead to an easy
+to overlook bug for anyone who does try to layer RT onto
+the LTSI baseline.
+
+Update it to use the currently used define name by RT.
