Subject: The 3G (or nG) Kernel Memory Space Offset
Date: Tue, 29 Aug 2006 22:15:19 +0800 [thread overview]
Message-ID: <a2ebde260608290715o627c631uca67e5b84b8c0777@mail.gmail.com> (raw)
The Linux kernel permenantly map 3-4G linear memory space to 0-4G
physical memory space. My question is that what is the rationality
behind this counterintuitive mapping. Is this just some personal
choice for the earlier kernel developers?
