Wysocki" , Jiri Kosina , Josh Poimboeuf , AKASHI Takahiro , Will Deacon From: "Steven Rostedt (Red Hat)" Nothing sets function_trace_stop to disable function tracing anymore. Remove the check for it in the arch code. arm64 was broken anyway, as it had an ifdef testing CONFIG_HAVE_FUNCTION_TRACE_MCOUNT_TEST which is only set if the arch supports the code (which it obviously did not), and it was testing a non existent ftrace_trace_stop instead of function_trace_stop.
