+          SmartMIPS is a extension of the MIPS32 architecture aimed at
+          increased security at both hardware and software level for
+          smartcards.  Enabling this option will allow proper use of the
+          SmartMIPS instructions by Linux applications.  However a kernel with
+          this option will not work on a MIPS core without SmartMIPS core.  If
+          you don't know you probably don't have SmartMIPS and should say N
+          here.
