#     Merge branch 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler updates from Thomas Gleixner:
#      "Third more careful attempt for this set of fixes:
#     
#        - Prevent a 32bit math overflow in the cpufreq code
#     
#        - Fix a buffer overflow when scanning the cgroup2 cpu.max property
#     
#        - A set of fixes for the NOHZ scheduler logic to prevent waking up
#          CPUs even if the capacity of the busy CPUs is sufficient along with
#          other tweaks optimizing the behaviour for asymmetric systems
#          (big/little)"
#     
#     * 'sched-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       sched/fair: Skip LLC NOHZ logic for asymmetric systems
#       sched/fair: Tune down misfit NOHZ kicks
#       sched/fair: Comment some nohz_balancer_kick() kick conditions
#       sched/core: Fix buffer overflow in cgroup2 property cpu.max
#       sched/cpufreq: Fix 32-bit math overflow
