1.CPU需要判断自己当前所处的模式，根据CPL寄存器的值执行不同操作。如果CPL表明目前正处于内核态，则不需要作切换，相反，如果CPL表明目前是用户态，那么需要将自己标为标为内核态。当然，在标记自己之前，必然会存在一些寄存器的保存以便日后恢复。
2. 需要做一些现场保护工作，就是把当前的寄存器存起来以便恢复。这个是跟用户态和内核态无关的，而是CPU当前所处的一个状态的信息保存。

1. 解压缩，把未压缩的内核包放在RAM的指定地址，然后从这个地址开始执行。
2.体系结构相关的初始化，初始化的目的也是为启动内核做准备，包括页表初始化啊，MMU,Cache，TLB等的初始化啊，最终在完成这些准备工作后跳转到start_kernel开始真]]>https://blog.youkuaiyun.com/IamGooday/article/details/4453381https://blog.youkuaiyun.com/IamGooday/article/details/4453381IamGoodaySun, 16 Aug 2009 20:28:00 +0800https://blog.youkuaiyun.com/IamGooday/article/details/4451058https://blog.youkuaiyun.com/IamGooday/article/details/4451058IamGoodaySun, 16 Aug 2009 09:41:00 +0800https://blog.youkuaiyun.com/IamGooday/article/details/4448633https://blog.youkuaiyun.com/IamGooday/article/details/4448633IamGoodaySat, 15 Aug 2009 09:19:00 +0800https://blog.youkuaiyun.com/IamGooday/article/details/4211059https://blog.youkuaiyun.com/IamGooday/article/details/4211059IamGoodaySat, 23 May 2009 17:15:00 +0800https://blog.youkuaiyun.com/IamGooday/article/details/4210916https://blog.youkuaiyun.com/IamGooday/article/details/4210916IamGoodaySat, 23 May 2009 16:01:00 +0800
