| Subject | [PATCH 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.
