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. 

Patches [2] to [4] will add a perf trace point "power:powernv_throttle" and
sysfs throttle counter stats in /sys/devices/system/cpu/cpufreq/chipN.
Patch [1] 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.

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

Also you shouldn't use --in-reply-to for the new versions of a
multiple patch series. Just use a new thread.
