Patch [4] in this series appears to be still being worked, and there is
some implication in the conversation that further revisions maybe
forthcoming.  Can we confirm these four are all that are needed at this
time.

Title:
  Add cpuidle-powernv upstream bug fixes to fix kernel regression due to
  cpuidle in 15.04 kernel

Status in linux package in Ubuntu:
  Confirmed

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?
