From 7110d40fbf27b1fafe70e3cd560f53ca7be094a5 Mon Sep 17 00:00:00 2001
From: Stefan Reinauer <stepan@coresystems.de>
Date: Tue, 3 Nov 2009 14:59:43 +0000
Subject: x86emu: Add support for the following opcodes:

* SMSW
* INVD/WBINVD
* RDMSR/WRMSR
* CPUID

The implementation is kept very simple (mostly dummies) but it should get
us successfully through the Poulsbo VGA OPROM code in order to determine
further requirements.

Also, fix up a lot of warnings (mostly about missing prototypes for
functions that should be static anyways)

This version adds a break in smsw that was missing in the patch that was sent
to the list.
