编译出错提示如下：

之前也make clean 和make dep ，make menuconfig 都没出错，最后make 编译时出现上面的错误，不知道是啥原因。
------解决方案--------------------
没有声明大小端?
------解决方案--------------------
从你代码来看，好像没有定义大小端的宏。你查一下__LITTLE_ENDIAN和__BIG_ENDIAN两个宏是不是定了，
------解决方案--------------------
没有声明大小端
------解决方案--------------------
看代码就知道宏__LITTLE_ENDIAN或__BIG_ENDIAN未定义，接着去查看asm/byteorder.h头文件即可。它一般会引用内核源码中的include/linux/byteorder/big_endian.h或include/linux/byteorder/little_endian.h文件，极少可能出现文件缺失的情况，错误很可能出现在解压或配置时。
