From: Torsten Duwe <duwe@xxxxxx>
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, ftrace and its helper files.
* arch/powerpc/kernel/Makefile,
arch/powerpc/lib/Makefile:
- remove -mprofile-kernel from low level, boot code and
code-patching objects' CFLAGS.
