Heteregeneous ARM platform uses arch_scale_freq_power function to reflect the relative capacity of each core
I think I've pointed out before that this breaks x86.. you need a patch killing at that stuff before this.
In v3.4, x86 hasn't got any specific declaration for arch_scale_freq_power so it would now use the weak arch_scale_freq_power which calls default_scale_freq_power. Isn't it enough ?
