> I think you should also remove CFLAGS_setup.o from kernel/Makefile, as I think it was there solely for the correctness of setup_vm. As setup_vm is now in mm/init.o, the old CFLAGS probably isn't needed and should be removed in the same patch. Disclaimer: I haven't tested it.

Sure, I will remove it in v2 patch. Thanks for catching.
