Subject: [RFC][PATCH 0/2] ftrace: Add modify_ftrace_direct()

As discussed with Alexei, here's a simple implementation of
modify_ftrace_direct() without the need for any architecture changes.

Steven Rostedt (VMware) (2):
      ftrace: Add modify_ftrace_direct()
      ftrace/samples: Add a sample module that implements modify_ftrace_direct()
