COMMON symbol warnings

After my compile run with __CHECK_ENDIAN__ the modules were built and I
got:

WARNING: "iwl_param_debug" [drivers/net/wireless/iwl3945] is COMMON symbol
WARNING: "iwl_param_disable_hw_scan" [drivers/net/wireless/iwl3945] is COMMON symbol
WARNING: "iwl_param_hwcrypto" [drivers/net/wireless/iwl3945] is COMMON symbol

WARNING: "zd_workqueue" [drivers/net/wireless/zd1211rw/zd1211rw] is COMMON symbol

any idea what that means? It's from scripts/mod/modpost.c:
        switch (sym->st_shndx) {
        case SHN_COMMON:
                warn("\"%s\" [%s] is COMMON symbol\n", symname, mod->name);
                break;
