Subject: uml: create as-layout.h
X-Git-Tag: v2.6.22-rc1~875
X-Git-Url: http://git.rot13.org/?p=powerpc.git;a=commitdiff_plain;h=4ff83ce1114827f707b7f1f4f2e5f69de9df94ac

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.
