Print message 1) only if secure rx51 smc instruction is called or 2) print message always (also if smc is not called). With that patch message is printed (enabled/disabled) only if device is rx51 and device type is HS. For information it is also good to know that in qemu that special secure smc instruction was not called. -- Pali Rohár pali.rohar@...il.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
