Here is the result of stap ... -p2 (probe part)
---
# probes
kernel.function("sys_epoll_wait@fs/eventpoll.c:1249")? /* pc=_stext+0xca908 */
/* <- syscall.epoll_wait = kernel.function("compat_sys_epoll_wait")?,
kernel.function("SyS_epoll_wait")!, kernel.function("sys_epoll_wait")? <-
syscall.epoll_wait */
# locals
argstr:string
{
(argstr) = (sprintf("%d, %p, %d, %d", _dwarf_tvar_get_epfd_4(),
_dwarf_tvar_get_events_5(), _dwarf_tvar_get_maxevents_6(),
_dwarf_tvar_get_timeout_7()))
printf("%s\\n", argstr)
exit()
}

And /proc/kallsyms said;
c0402000 T _stext
So, actual probing address is 0xc04cc908 (sys_epoll_wait+0).
