将所有的__initdata标志去掉
根文件系统挂载成功
__initdata，和__init的作用基本上一样，不过它是针对变量而不是函数的。
__init 宏最常用的地方是驱动模块初始化函数的定义处，其目的是将驱动模块的初始化函数放入名叫.init.text的输入段。对于__initdata来说，用于数据定义，目的是将数据放入名叫.init.data的输入段。这两个段中只能被使用一次，使用完后要释放回收这两个段内存空间
所以在内核启动过程中有这么一句
Freeing init memory: 100K
就是表示释放init段内存的大小

同样DM9000部分也一样，不要__initdata这个标志，不然有可能网络不能连接
修改过后mach-mini2440.c中nand和dm9000部分代码
