From: Yong Zhang <yong.zhang@windriver.com>
Now /proc/timer_stats will show add_timer() as the start_site: 23, 0 swapper add_timer (peer_check_expire) 23, 0 swapper add_timer (addrconf_verify)
This is because add_timer() -> mod_timer() -> __mod_timer(), but mod_timer() is not inlined. So add_timer() is showed. Call timer_stats_timer_set_start_info() explicitly to record the real start_site.
After this change, timer_stats_timer_set_start_info() in workqueue.c can be removed.
