# 
#     Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler updates from Ingo Molnar:
#      "These were the main changes in this cycle:
#     
#        - More -rt motivated separation of CONFIG_PREEMPT and
#          CONFIG_PREEMPTION.
#     
#        - Add more low level scheduling topology sanity checks and warnings
#          to filter out nonsensical topologies that break scheduling.
#     
#        - Extend uclamp constraints to influence wakeup CPU placement
#     
#        - Make the RT scheduler more aware of asymmetric topologies and CPU
#          capacities, via uclamp metrics, if CONFIG_UCLAMP_TASK=y
#     
#        - Make idle CPU selection more consistent
#     
#        - Various fixes, smaller cleanups, updates and enhancements - please
#          see the git log for details"
