This is a feature request to include the following patches in 14.04.03
kernel.

[1] 74aa51b5ccd39753 cpuidle: powernv: Populate cpuidle state details by querying the device-tree 
(3.18 upstream)

[2] cpuidle/powernv: Read target_residency value of idle states from DT if available
https://lkml.org/lkml/2015/2/3/23

[3] tick/broadcast-hrtimer : Fix suspicious RCU usage in idle loop
http://linuxppc.10917.n7.nabble.com/PATCH-tick-broadcast-hrtimer-Fix-suspicious-RCU-usage-in-idle-loop-td89675.html

[1] and [2] patches provide fixes to read the latency and
target_residency values of different idle states from the device tree if
they are present in the device tree. This fix will avoid cpu from
aggressively  entering into fastsleep.

[3] is an important fix against a kernel regression down the cpuidle
path which was reported in the community.
