Subject: [PATCH v2 3/4] ppc64 ftrace_with_regs: spare early boot and low level code
Date: Fri, 19 Jun 2015 16:09:16 +0200 [thread overview]
Message-ID: <20150619140916.GC8824@lst.de> (raw)
In-Reply-To: <20150619140403.GA8681@lst.de>
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 (remove it from CFLAGS), equally with
time.o and ftrace itself.
* arch/powerpc/kernel/Makefile:
- remove -mprofile-kernel from low level and boot code objects'
CFLAGS for FUNCTION_TRACER configurations.
