Subject: [PATCH 3/4] ppc64 ftrace_with_regs: spare early boot and low level code
Date: Thu, 11 Jun 2015 12:01:25 +0200	[thread overview]
Message-ID: <20150611100125.GD4492@lst.de> (raw)
In-Reply-To: <20150611095338.GA4492@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.
