将启动参数拷贝到"zeropage"
--------------------------------------------------------------------------------
We will start from the `main` routine in "main.c". First function which is called in `main` is [`copy_boot_params(void)`](https://github.com/torvalds/linux/blob/master/arch/x86/boot/main.c#L30). It copies the kernel setup header into the field of the `boot_params` structure which is defined in the [arch/x86/include/uapi/asm/bootparam.h](https://github.com/torvalds/linux/blob/master/arch/x86/include/uapi/asm/bootparam.h#L113).
让我们从`main`函数开始看起，这个函数中，首先调用了[`copy_boot_params(void)`](https://github.com/torvalds/linux/blob/master/arch/x86/boot/main.c#L30)。 这个函数将内存设置信息拷贝到`boot_params`结构的相应字段。大家可以在[arch/x86/include/uapi/asm/bootparam.h](https://github.com/torvalds/linux/blob/master/arch/x86/include/uapi/asm/bootparam.h#L113)找到`boot_params`结构的定义。
