I had problems applying these.
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
