This makes them not selectable as default governors. > oversight I should cook up a patch for? Looks like the Kconfig and a bit > of cut-n-paste in include/linux/cpufreq.h is all that's needed?

Thomas Renninger has posted patches on cpufreq-devel to accomplish that. cheers -- mattia :wq! - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
