If you look at global_noreturns in tools/objtool/check.c:
 145   static const char * const global_noreturns[] = {
 146     "__stack_chk_fail",
 147     "panic",
 148     "do_exit",
 149     "do_task_dead",
 150     "__module_put_and_exit",
 151     "complete_and_exit",
 152     "__reiserfs_panic",
 153     "lbug_with_loc",
 154     "fortify_panic",
 155     "usercopy_abort",
 156     "machine_real_restart",
 157     "rewind_stack_do_exit",
 158     "kunit_try_catch_throw",
 159   };

Whether they occur or not at the position you ask; I haven't checked.
