Subject: [PATCH 13/13 v2] ftrace: remove notrace from arch ftrace file
Date: Wed, 22 Oct 2008 17:27:34 -0400 [thread overview]
Message-ID: <20081022213553.396121903@goodmis.org> (raw)
In-Reply-To: 20081022212721.167005680@goodmis.org
[-- Attachment #1: ftace-remove-notrace.patch --]
[-- Type: text/plain, Size: 5301 bytes --]
The entire file of ftrace.c in the arch code needs to be marked
as notrace. It is much cleaner to do this from the Makefile with
CFLAGS_REMOVE_ftrace.o.
Signed-off-by: Steven Rostedt <srostedt@redhat.com>
