This look like the problem you are running into
http://lists.xensource.com/archives/html/xen-users/2010-12/msg00166.html

(A problem with your git tree for the kernel.)

Based on getting an error here and looking above.

This appears to be a question that is probably better addressed on the
xen-users list. It is better to post there first unless you are sure
something is really broken.

The Xen code is tested often by many users and developers all over the
world. I'm pretty sure we would figure out pretty quickly if make
world was broken :-)

Hope the suggestions above help solve your problem.

Thanks,
Todd
