Good point.

Right now you need a module.c in each architecture defining all these
functions. However, I think it would be cool if we didn't need this
all of them. In case of openrisc, the architecture should only have
to define a apply_relocate_add() function.
Jonas, could you add a default implementation for each of the functions
for include/linux/moduleloader.h, so that you only have to provide the
one function?
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
Then each architecture that needs a special version can do
#define module_alloc(size) module_alloc(size)
in their respective asm/module.h
