From: Steven Rostedt <rost...@goodmis.org>
The trace events sched_move_numa, sched_swap_numa and sched_stick_numa are
only used when CONFIG_NUMA_BALANCING is enabled. Put an #ifdef guard
around the definitions of these trace events so they are not defined when
numa balancing is not enabled, otherwise they waste a bit of memory being
unused.
