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

Status in linux package in Ubuntu:

Bug description:
  This is a feature request to include the following patches in 15.04

  [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
  [4] tick/hotplug: Handover time related duties before cpu offline

  [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?
