  sched_ext: idle: Handle migration-disabled tasks in idle selection (2025-07-17 08:19:38 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v6.16-rc6

- Fix handling of migration disabled tasks in default idle selection.

- update_locked_rq() called __this_cpu_write() spuriously with NULL when @rq
  was not locked. As the writes were spurious, it didn't break anything
  directly. However, the function could be called in a preemptible leading
  to a context warning in __this_cpu_write(). Skip the spurious NULL writes.

- Selftest fix on UP.
