Re: Xen dom0 regression in HEAD

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

FreeBSD 8 uses the clflush instruction which Xen didn't emulate.
This has been fixed upstream.

Xen-unstable: http://xenbits.xensource.com/xen-unstable.hg/rev/d18e6a6c618a

Xen 4.0:
http://xenbits.xensource.com/staging/xen-4.0-testing.hg?rev/2b2e7b4e0267

One need to backport and apply the patch to xenkernel33.
