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.
