Subject: [PATCH v7 05/10] ppc64 ftrace_with_regs: spare early boot and low level
Date: Mon, 25 Jan 2016 16:30:35 +0100 [thread overview]
Message-ID: <20160204162059.0BAA5692DD@newverein.lst.de> (raw)
In-Reply-To: <20160204161527.5F3AC692CD@newverein.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.
