I noticed that kernel/module.c already has this:

unsigned int __weak arch_mod_section_prepend(struct module *mod,
                                             unsigned int section)


Is using a __weak attribute on the default (generic) implementations a
better approach?

With the __weak variant this wouldn't be necessary...
