In POWER8, OCC(On-Chip-Controller) can throttle the frequency of the
CPU when the chip crosses its thermal and power limits. Currently,
powernv-cpufreq driver detects and reports this event as a console
message. Some machines may not sustain the max turbo frequency in all
conditions and can be throttled frequently. This can lead to the
flooding of console with throttle messages. So this patchset aims to
redesign the presentation of this event via sysfs counters and
tracepoints. And it also fixes couple of bugs reported in the driver.

- Patch [1] fixes a memory leak bug
- Patch [2] fixes the cpu hot-plug bug in powernv_cpufreq_work_fn().
- Patch [3] solves a bug in powernv_cpufreq_throttle_check(), which
  calls in to cpu_to_chip_id() in hot path which reads DT every time
  to find the chip id.
- Patches [4] to [6] will add a perf trace point
  "power:powernv_throttle" and sysfs throttle counter stats in
  /sys/devices/system/cpu/cpufreq/chipN.

Looks good to me. You've got the reviews and acks you need.
