  locking: rtmutex: Fix wake_q logic in task_blocks_on_rt_mutex (2024-12-02 12:01:29 +0100)

----------------------------------------------------------------
- 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
