先说说我的编译步骤：先从网上下载了linux-2.6.19的源代码，然后拷贝到/usr/src目录下，解压，然后执行make distclean命令。之后执行make menuconfig命令，在菜单中，未作任何修改直接点Exit，保存退出（之所以未在该菜单下做配置，是不熟悉配置，想后面用X86里面的默认配置文件）。执行后在linux-2.6.19目录下生成了.config的文件。
之后执行命令 cd /arch/x86/configs,执行后，用cp指令将configs里X86的默认配置文件拷贝到linux-2.6.19目录下的.config文件中。
下面就执行make bzImage编译内核，之后就提示下面信息：
[root@localhost linux-2.6.29]# make bzImage

怪哉，我已经使用的X86的默认配置文件，怎么还提示俺配置信息呢？而且配置信息里System Type竟然都是跟ARM相关的。我打开内核目录下的.config文件，看到里面的信息确实是跟X86相关的啊，.config的信息如下：
# Automatically generated make config: don't edit
# Linux kernel version: 2.6.27-rc5
