#     Merge tag 'sched_urgent_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull scheduler fixes from Borislav Petkov:
#     
#      - Avoid touching ~100 config files in order to be able to select the
#        preemption model
#     
#      - clear cluster CPU masks too, on the CPU unplug path
#     
#      - prevent use-after-free in cfs
#     
#      - Prevent a race condition when updating CPU cache domains
#     
#      - Factor out common shared part of smp_prepare_cpus() into a common
#        helper which can be called by both baremetal and Xen, in order to fix
#        a booting of Xen PV guests
#     
#     * tag 'sched_urgent_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
