Add a snapshot of all changes associated with the HMP scheduler ported over to the latest kernel version. This will allow proper big Little scheduling for targets that will use this kernel version. The msm-4-4 snapshot is taken at commitcc60f0790f27 (sched: constrain HMP scheduler tunable range with in better way). Please note that this is not an exact snapshot; certain HMP related code has been removed. This includes redundant code, useless CONFIG options, rarely taken error code paths, runtime enable/disable support for the HMP scheduler.
