Pull tracing fix from Steven Rostedt:
"Some of the ftrace internal events use a zero for a data size of a
field event. This is increasingly important for the histogram trigger
work that is being extended.
While auditing trace events, I found that a couple of the xen events
were used as just marking that a function was called, by creating a
static array of size zero. This can play havoc with the tracing
features if these events are used, because a zero size of a static
array is denoted as a special nul terminated dynamic array (this is
what the trace_marker code uses). But since the xen events have no
size, they are not nul terminated, and unexpected results may occur.
As trace events were never intended on being a marker to denote that a
function was hit or not, especially since function tracing and kprobes
can trivially do the same, the best course of action is to simply
remove these events"
