Linus Torvalds 63ce50fff9 Scheduler changes for v6.7 are:
- Fair scheduler (SCHED_OTHER) improvements:
 
     - Remove the old and now unused SIS_PROP code & option
     - Scan cluster before LLC in the wake-up path
     - Use candidate prev/recent_used CPU if scanning failed for cluster wakeup
 
  - NUMA scheduling improvements:
 
     - Improve the VMA access-PID code to better skip/scan VMAs
     - Extend tracing to cover VMA-skipping decisions
     - Improve/fix the recently introduced sched_numa_find_nth_cpu() code
     - Generalize numa_map_to_online_node()
 
  - Energy scheduling improvements:
 
     - Remove the EM_MAX_COMPLEXITY limit
     - Add tracepoints to track energy computation
     - Make the behavior of the 'sched_energy_aware' sysctl more consistent
     - Consolidate and clean up access to a CPU's max compute capacity
     - Fix uclamp code corner cases
 
  - RT scheduling improvements:
 
     - Drive dl_rq->overloaded with dl_rq->pushable_dl_tasks updates
     - Drive the ->rto_mask with rt_rq->pushable_tasks updates
 
  - Scheduler scalability improvements:
 
     - Rate-limit updates to tg->load_avg
     - On x86 disable IBRS when CPU is offline to improve single-threaded performance
     - Micro-optimize in_task() and in_interrupt()
     - Micro-optimize the PSI code
     - Avoid updating PSI triggers and ->rtpoll_total when there are no state changes
 
  - Core scheduler infrastructure improvements:
 
     - Use saved_state to reduce some spurious freezer wakeups
     - Bring in a handful of fast-headers improvements to scheduler headers
     - Make the scheduler UAPI headers more widely usable by user-space
     - Simplify the control flow of scheduler syscalls by using lock guards
     - Fix sched_setaffinity() vs. CPU hotplug race
 
  - Scheduler debuggability improvements:
     - Disallow writing invalid values to sched_rt_period_us
     - Fix a race in the rq-clock debugging code triggering warnings
     - Fix a warning in the bandwidth distribution code
     - Micro-optimize in_atomic_preempt_off() checks
     - Enforce that the tasklist_lock is held in for_each_thread()
     - Print the TGID in sched_show_task()
     - Remove the /proc/sys/kernel/sched_child_runs_first sysctl
 
  - Misc cleanups & fixes
