I want to add a file in kernel tree but want to compile it without O2. For example, if I add a file tmp.c in net/core/ directory and modify net/core/Makefile obj list, tmp.c is compiled but with all default options which include O2 also. How can I edit net/core/Makefile to compile tmp.c without O2?
