-	  This adds the cpufreq driver for SuperH. Any CPU that supports
-	  clock rate rounding through the clock framework can use this
-	  driver. While it will make the kernel slightly larger, this is
-	  harmless for CPUs that don't support rate rounding. The driver
-	  will also generate a notice in the boot log before disabling
-	  itself if the CPU in question is not capable of rate rounding.
-
-	  For details, take a look at <file:Documentation/cpu-freq>.
-
-	  If unsure, say N.
