Subject: [for-next][PATCH 5/5] function_graph: Place ftrace_graph_entry_stub() prototype in
 include/linux/ftrace.h

From: "Steven Rostedt (VMware)" <rostedt@...dmis.org>

ftrace_graph_entry_stub() is defined in generic code, its prototype should
be in the generic header and not defined throughout architecture specific
code in order to use it.
