Pkg xen devel - Feb 2014 - Bug#737905: Xen: hvmloader causes immediate VCPU triple fault with SeaBIOS 1.7.4

Package: xen-utils-4.3
Version: 4.3.0-3
Severity: important
Tags: upstream patch

When using Xen compiled with seabios-1.7.4-1 (now in unstable/testing), HVMs
fail immediately upon starting with a VCPU triple fault:
(XEN) HVM1: Loading SeaBIOS ...
(XEN) hvm.c:1253:d1 Triple fault on VCPU0 - invoking HVM shutdown action 1.

This is because SeaBIOS can now be greater than 128k, which breaks an assumption
in the hvmloader code.  This is fixed upstream in 4.3.1, but can be fixed in
4.3.0 by backporting the following commit:
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=5f2875739beef3a75c7a7e8579b6cbcb464e61b3

I have tested this commit (in the form of the attached patch) on top of 4.3.0-3,
and confirmed it fixes the issue.
