编译内核出现undefined reference to `__moddi3'的错误

[qq_28809597]

可是我把取余的语句换掉了为什么还报这个错呢？
在sys.c里我添加的函数

asmlinkage long long sys_mycall(long long num){//在此处加入代码
	long long result;
	if (num - (num / 2) == 1){//is odd number
		result = num - 100000 * (num / 100000);
	}
	else{//is even number
		result = num - 10000 * (num / 10000);
	
	}
	printk("This is my student id is %lld.\n", result);
	//printk("current pid is:%d.\n",current->pid);
	return result;
}
