#     Merge tag 'sched-core-2020-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler updates from Ingo Molnar:
#     
#      - Improve uclamp performance by using a static key for the fast path
#     
#      - Add the "sched_util_clamp_min_rt_default" sysctl, to optimize for
#        better power efficiency of RT tasks on battery powered devices.
#        (The default is to maximize performance & reduce RT latencies.)
#     
#      - Improve utime and stime tracking accuracy, which had a fixed boundary
#        of error, which created larger and larger relative errors as the
#        values become larger. This is now replaced with more precise
#        arithmetics, using the new mul_u64_u64_div_u64() helper in math64.h.
#     
#      - Improve the deadline scheduler, such as making it capacity aware
#     
#      - Improve frequency-invariant scheduling
#     
#      - Misc cleanups in energy/power aware scheduling
#     
#      - Add sched_update_nr_running tracepoint to track changes to nr_running
#     
#      - Documentation additions and updates
#     
#      - Misc cleanups and smaller fixes
#
