Linus Torvalds 75b607fab3 sched_ext: Fixes for v6.12-rc2 
- ops.enqueue() didn't have a way to tell whether select_task_rq_scx() and
   thus ops.select() were skipped. Some schedulers were incorrectly using
   SCX_ENQ_WAKEUP. Add SCX_ENQ_CPU_SELECTED and fix scx_qmap using it.
 
 - Remove a spurious WARN_ON_ONCE() in scx_cgroup_exit().
 
 - Fix error information clobbering during load.
 
 - Add missing __weak markers to BPF helper declarations.
 
 - Doc update.
