  [PATCH v2 3/4] ppc64 ftrace_with_regs: spare early boot and low  level code Torsten Duwe <duwe@lst.de> - 2015-06-19 16:10 +0200

#1168802 — [PATCH v2 3/4] ppc64 ftrace_with_regs: 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 (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.
