[PATCH v3 00/12] cpufreq: use __free() for all cpufreq_cpu_get() references

[Zihuan Zhang]

This patchset converts all remaining cpufreq users to rely on the
__free(put_cpufreq_policy) annotation for policy references, instead of
calling cpufreq_cpu_put() manually.

Motivation:
- Reduce the chance of reference counting mistakes
- Make the code more consistent with the latest kernel style
- behavior remains the same, but reference counting is now safer 
  and easier to maintain.

The changes are split into 12 patches as they touch different subsystems
and are maintained by different people. There is no functional change.

V3:
 - drop patch 'KVM: x86: Use __free(put_cpufreq_policy) for policy reference'
 - removed 5 patches which has been applied
 - Consolidate CPUFreq policy assignments and allocations into one line,
   suggested by Ben Horgan
 - Change cpu_has_cpufreq() return type to bool, following Rafael's suggestion
 - Change the title to 'Use scope-based cleanup helper'

V2:
 - Fix compile error in powernv-cpufreq.c
 - Split patch to separate logical changes
