To identify what code is compiled into modules during a kernel build, one can look for the presence of the -DKBUILD_MODFILE and -DKBUILD_MODNAME options in the compile command lines. A simple grep in .*.cmd files for those options is sufficient for this. Unfortunately, these options are only passed when compiling C source files. Various modules also include objects built from assembler source, and these options are not passed in that case. Adding $(modfile_flags) to modkern_aflags (similar to modkern_cflahs), and adding $(modname_flags) to a_flags (similar to c_flags) makes it possible to identify which objects are compiled into modules for both C and assembler soure files.
