Sorry Stephen, the merged result should look like what's contained in
linux-integrity/next-upstreamed-patches:

int ima_module_check(struct file *file)
{
        if (!file) {
                if ((ima_appraise & IMA_APPRAISE_MODULES) &&
                    (ima_appraise & IMA_APPRAISE_ENFORCE)) {
#ifndef CONFIG_MODULE_SIG_FORCE
                        return -EACCES; /* INTEGRITY_UNKNOWN */
#endif
                }
                return 0;
        }
        return process_measurement(file, file->f_dentry->d_name.name,
                                   MAY_EXEC, MODULE_CHECK);
}

thanks,

Mimi
