correct me if i'm wrong. But what I understand are you saying that x86 linux
doesn't use segmented memory model. Are you sure?(i could be wrong in
understanding sorry) Because I'm reading the book "Understanding Linux 
Kernel"
and the author is saying that linux uses segmented memory model. I wasn't 
sure
whether linux uses seg model by default so i asked the question.

Again thanks.
