[for-next][PATCH 28/32] tracing: Remove function_trace_stop and HAVE_FUNCTION_TRACE_MCOUNT_TEST

[Steven Rostedt <rostedt@goodmis.org>]

[-- Attachment #1: 0028-tracing-Remove-function_trace_stop-and-HAVE_FUNCTION.patch --]
[-- Type: text/plain, Size: 1680 bytes --]

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

All users of function_trace_stop and HAVE_FUNCTION_TRACE_MCOUNT_TEST have
been removed. We can safely remove them from the kernel.
