The Makefile now examine $(LINUX)/.config to see what modules need to be compiled. It compiles only those modules which were either not configured in at all, or were built as modules (ie. drivers which are built-in in the kernel are not built, as they can not be overruled). The above is still potentially dangerous, if we break the interface of our modules. Still, it is much better than it was.
