From badc76527f7e29302f0bde3d366c59101fb2ab87 Mon Sep 17 00:00:00 2001
From: Alexander van Heukelum <heukelum@mailshack.com>
Date: Wed, 2 Jul 2008 01:30:30 +0200
Subject: [PATCH] x86: traps_xx: shuffle headers and globals

Reorder headers and collect globals in traps_32.c and traps_64.c

Code size and data size are unaffected by the changes. Code
itself is changed due to different ordering of data and bss.
The bss segment changed size due to a change in the packing
of the variables.
