    sched: Final power vs. capacity cleanups · ca8ce3d0
    Nicolas Pitre authored
    It is better not to think about compute capacity as being equivalent
    to "CPU power".  The upcoming "power aware" scheduler work may create
    confusion with the notion of energy consumption if "power" is used too
    liberally.
    
    This contains the architecture visible changes.  Incidentally, only ARM
    takes advantage of the available pow^H^H^Hcapacity scaling hooks and
    therefore those changes outside kernel/sched/ are confined to one ARM
    specific file.  The default arch_scale_smt_power() hook is not overridden
    by anyone.
    
    Replacements are as follows:
    
    	arch_scale_freq_power  --> arch_scale_freq_capacity
    	arch_scale_smt_power   --> arch_scale_smt_capacity
    	SCHED_POWER_SCALE      --> SCHED_CAPACITY_SCALE
    	SCHED_POWER_SHIFT      --> SCHED_CAPACITY_SHIFT
    
    The local usage of "power" in arch/arm/kernel/topology.c is also changed
    to "capacity" as appropriate.
