+ 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.
