lock_release_holdtime() will access percpu variable, so every lock release may trigger the hang if CONFIG_LOCK_STAT is enabled, and there are many lock acquire/release before setup_arch. No detailed backtrace since only early_printk can work at that time. > description makes it sounds like a caller bug, so it would be good to > document a valid user of per-cpu before cpu_init().
