Merge tag 'sched_urgent_for_v6.13_rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull scheduler fixes from Borislav Petkov:

 - Remove wrong enqueueing of a task for a later wakeup when a task
   blocks on a RT mutex

 - Do not setup a new deadline entity on a boosted task as that has
   happened already

 - Update preempt= kernel command line param

 - Prevent needless softirqd wakeups in the idle task's context

 - Detect the case where the idle load balancer CPU becomes busy and
   avoid unnecessary load balancing invocation

 - Remove an unnecessary load balancing need_resched() call in
   nohz_csd_func()

 - Allow for raising of SCHED_SOFTIRQ softirq type on RT but retain the
   warning to catch any other cases

 - Remove a wrong warning when a cpuset update makes the task affinity
   no longer a subset of the cpuset
