I notice that module.h contains stuff like:

#define MODULE_GENERIC_TABLE(gtype,name) \
extern const struct gtype##_id __mod_##gtype##_table \
__attribute__ ((unused, alias(__stringify(name))))

and even:

#define __MODULE_INFO(tag, name, info) \
static const char __module_cat(name,__LINE__)[] \
__attribute_used__ \
__attribute__((section(".modinfo"),unused)) = __stringify(tag) "=" info

My understanding is that we shouldn't be using __attribute__((unused))
in either of these - can someone confirm.

The second one looks fairly dodgy since we're telling a compiler that
it's both used and unused. That sounds a bit like a HHGTTG puzzle (you
have tea and no tea.)
