From 4ff83ce1114827f707b7f1f4f2e5f69de9df94ac Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sun, 6 May 2007 14:51:08 -0700 Subject: [PATCH] uml: create as-layout.h This patch moves all the the symbols defined in um_arch.c, which are mostly boundaries between different parts of the UML kernel address space, to a new header, as-layout.h. There are also a few things here which aren't really related to address space layout, but which don't really have a better place to go.
