Subject: [ PATCH 4/7 ] 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.
Signed-off-by: Jeff Dike <jdike@...ux.intel.com>
