Title: Add cpuidle-powernv upstream bug fixes to fix kernel regression due to cpuidle in 15.04 kernel Status in linux package in Ubuntu: New Bug description: This is a feature request to include the following patches in 15.04 kernel. [1] 92c83ff5b42b109 cpuidle/powernv: Read target_residency value of idle states from DT if available [2] 70734a786acfd1 driver/cpuidle-powernv: Avoid endianness conversions while parsing DT [3] tick/broadcast-hrtimer : Fix suspicious RCU usage in idle loop https://lkml.org/lkml/2015/3/18/185 [4] tick/hotplug: Handover time related duties before cpu offline https://patchwork.ozlabs.org/patch/435097/ [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] and [4] are important fixes against a kernel regression, cpu offline bug down the cpuidle path which was reported in the community Thanks for the new bug. I understand that patches [2] and [3] are not accepted upstream yet, right?
