Merge drm/drm-next into drm-intel-next

Sync to v6.16-rc1, among other things to get the fixed size GENMASK_U*()
and BIT_U*() macros.

- * hung_task_mutex.c - Sample code which causes hung task by mutex
- *
- * Usage: load this module and read `<debugfs>/hung_task/mutex`
- *        by 2 or more processes.
- *
- * This is for testing kernel hung_task error message.
- * Note that this will make your system freeze and maybe
- * cause panic. So do not use this except for the test.
