From ac694fda326e381d957a591b6b874afdbe8778e6 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Wed, 25 Jun 2014 14:41:21 -0400 Subject: arm64, ftrace: Remove check of obsolete variable function_trace_stop 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.
