The structure that gets placed in this section is the ftrace_event_call.
It consists only of pointers, a struct list_head, a couple of "int", and
a struct trace_event, which consists of: a struct hlist_node, a struct
list_head, an int, and a pointer.

None of these are more than "long" and I don't foresee them needing a
long long type. I think assuming that a long is the largest item should
due.

We can add a comment next to these structures specifying this
dependency, and hopefully it would be updated if we ever do include a
long long in them.
