64c12e0444fcc6b75eb49144ba46d43dbdc6bc8f is a nice patch from
Jason Baron, this patch introduces enter_syscall_print_##sname.

This patch only forgot to do some cleanups. My patch make up it:

fix event_enter_##sname->event
fix event_exit_##sname->event

remove unused event_syscall_enter and event_syscall_exit

Thanks,
Lai

    tracing: Add individual syscalls tracepoint id support

    The current state of syscalls tracepoints generates only one event id
    for every syscall events.

    This patch associates an id with each syscall trace event, so that we
    can identify each syscall trace event using the 'perf' too
