Title:
  Support for HMI (Hypervisor Maintenance Interrupt) handling in ubuntu
  14.10

Status in “linux” package in Ubuntu:
  Fix Committed
Status in “linux” source package in Utopic:
  Fix Committed

Bug description:
  ---Problem Description---
  There is no HMI feature support present in ubuntu distro currently. Upstream kernel now has support for HMI handling in Linux. We want push this support into ubuntu 14.10. The related upstream commit are listed below:

  db97eff powerpc/book3s: Fix endianess issue for HMI handling on napping cpus.
  bbdb760 powerpc/book3s: handle HMIs for cpus in nap mode.
  0ef95b4 powerpc/powernv: Invoke opal call to handle hmi.
  0869b6f powerpc/book3s: Add basic infrastructure to handle HMI in Linux.

  Please include these commits in ubuntu 14.10
   
  Canonical, the patches (cherry-picked) should apply fine over kernel 3.16
