Linus,

Please pull the latest sched-core-for-linus git tree from:

   # HEAD: af24bde8df2029f067dc46aff0393c8f18ff6e2f sched/uclamp: Add uclamp support to energy_compute()

The main changes in this cycle were:

 - Remove the unused per rq load array and all its infrastructure,
   by Dietmar Eggemann.

 - Add utilization clamping support by Patrick Bellasi. This is a 
   refinement of the energy aware scheduling framework with support for 
   boosting of interactive and capping of background workloads: to make 
   sure critical GUI threads get maximum frequency ASAP, and to make sure 
   background processing doesn't unnecessarily move to cpufreq governor 
   to higher frequencies and less energy efficient CPU modes.

 - Add the bare minimum of tracepoints required for LISA EAS regression 
   testing, by Qais Yousef - which allows automated testing of various 
   power management features, including energy aware scheduling.

 - Restructure the former tsk_nr_cpus_allowed() facility that the -rt 
   kernel used to modify the scheduler's CPU affinity logic such as 
   migrate_disable() - introduce the task->cpus_ptr value instead of 
   taking the address of &task->cpus_allowed directly - by Sebastian
   Andrzej Siewior.

 - Misc optimizations, fixes, cleanups and small enhancements - see the 
   Git log for details.

 Thanks,

	Ingo
