Subject[PATCH 3/3] tracing: Remove leftover FTRACE_ENABLE/DISABLE_MCOUNT enums
From: Steven Rostedt <srostedt@redhat.com>

The enums for FTRACE_ENABLE_MCOUNT and FTRACE_DISABLE_MCOUNT were
used as commands to ftrace_run_update_code(). But these commands
were used by the old nasty ftrace daemon that has long been slain.

This is a clean up patch to remove the references to these enums
and simplify the code a little.
