Applying [CPUFREQ][1/6] cpufreq: Add cpu number parameter to __cpufreq_driver_getavg() Applying [CPUFREQ][2/6] cpufreq: Change load calculation in ondemand for software coordination error: patch failed: drivers/cpufreq/cpufreq_ondemand.c:365 Can you rediff them on top of the next branch of git-cpufreq ? thanks, Dave -- http://www.codemonkey.org.uk
