Date: Wed, 3 Jun 2015 15:15:22 +0200 From: Torsten Duwe <duwe@....de> To: Michael Ellerman <mpe@...erman.id.au>, ppc-dev <linuxppc-dev@...ts.ozlabs.org> Cc: Jiri Kosina <jkosina@...e.cz>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Steven Rostedt <rostedt@...dmis.org> Subject: Re: [PATCH 3/4] ppc64 ftrace: spare early boot and low level code Using -mprofile-kernel on early boot code not only confuses the checker but is also useless, as the infrastructure is not yet in place. Proceed like with -pg, equally with time.o and ftrace itself.
