I think that an easy way to do that would be to add to kernel/module.c
code like:

#ifndef module_alloc
void *module_alloc(unsigned long size)
{
	return vmalloc(size);
}
#endif

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?

Then each architecture that needs a special version can do
#define module_alloc(size) module_alloc(size)
in their respective asm/module.h

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