Subject: [PATCH v5 7/9] ppc64 ftrace: disable profiling for some files
Date: Fri, 4 Dec 2015 14:57:22 +0100 [thread overview]
Message-ID: <20151204152848.2ABEA691D2@newverein.lst.de> (raw)
In-Reply-To: <20151204152419.28E0D691D2@newverein.lst.de>
This patch complements the "notrace" attribute for selected functions.
It adds -mprofile-kernel to the cc flags to be stripped from the command
line for code-patching.o and feature-fixups.o, in addition to "-pg"
Signed-off-by: Torsten Duwe <duwe@suse.de>
