I assume you have the .o file build somewhere as part of the normal kernel build. Then you in arch/powerpc/Makefile adds the following assignment: LDFLAGS_MODULE += arch/powerpc/lib/my_magic_file.o kbuild will then during the modpost stage link this file on all modules. To add the same file to the kernel just include it in a obj-y += my_magic_file.o One trap is that my_magic_file.o needs to be built for a modules build too. I think you need to assign it to always: always := my_magic_file.o to accomplish this. So in the end we will have: arch/powerpc/Makefile: LDFLAGS_MODULE += arch/powerpc/lib/my_magic_file.o arch/powerpc/lib/Makefile: always := my_magic_file.o obj-y += my_magic_file.o Let me know if this does address your question.
