This patchset intends to add frequency throttle reporting mechanism
to powernv-cpufreq driver when OCC throttles the frequency. OCC is an
On-Chip-Controller which takes care of the power and thermal safety of
the chip. The CPU frequency can be throttled during an OCC reset or
when OCC tries to limit the max allowed frequency. The patchset will
report such conditions so as to keep the user informed about reason
for the drop in performance of workloads when frequency is throttled.

Changes from v3:
- Rebased on top of 4.2-rc1
- Minor changes in patch 2,3,4,6 this does not change the
  functionality of the code
- 594fcb9ec9e powerpc/powernv: Expose OPAL APIs required by PRD
  interface , this patch fixes the build error due to which this
  series was initially dropped
  ERROR: ".opal_message_notifier_register"
  drivers/cpufreq/powernv-cpufreq.ko] undefined!
I have already Acked v3 of this and that applies to this one as well..
