#     Merge tag 'sched_urgent_for_v6.2_rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler fixes from Borislav Petkov:
#     
#      - Make sure the scheduler doesn't use stale frequency scaling values
#        when latter get disabled due to a value error
#     
#      - Fix a NULL pointer access on UP configs
#     
#      - Use the proper locking when updating CPU capacity
