From: Steven Rostedt <rost...@goodmis.org>
The events xdp_cpumap_kthread, xdp_cpumap_enqueue and xdp_devmap_xmit are
only called when CONFIG_BPF_SYSCALL is defined. As each event can take up
to 5K regardless if they are used or not, it's best not to define them
when they are not used. Add #ifdef around these events when they are not
used.

Note, I will be adding code soon that will make unused events cause a waring.
