      perf/ARM: Use common PMU interrupt disabled code · edcb4d3c
      由 Vince Weaver 提交于 
      Make the ARM perf code use the new common PMU interrupt disabled code.

This allows perf to work on ARM machines without a working PMU
interrupt (for example, raspberry pi).

      sched: Final power vs. capacity cleanups · ca8ce3d0
      由 Nicolas Pitre 提交于 
      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.
