From: Torsten Duwe <redacted> 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.
