Reason for %ss==%ds?

[nascent mind <nascent.mind@xxxxxxxxx>]

Hi,

   I am trying to understand the boot process of the kernel and I am not able to understand why the stack segment should be equal to the data segment here http://lxr.linux.no/#linux+v2.6.31.2/arch/x86/boot/header.S#L260 . Can somebody explain this? Wouldn't it overlap with the code segment?

Thanks.
