Oh, right, and that description is either too little or possibly unnecessary, with a change made to "tools/cpufreq: extract CPPC para from cpufreq para" (both as per my v9 comments). IOW v8 also isn't exactly what would want to go in. All not a good basis for rushing this in at (later than) the last minute. Jan
