Try building without CONFIG_SMP, it doesn't support that yet.

Yep, this tree:

  http://git.et.redhat.com/?p=xen-pvops-64.git

is the work-in-progress x86_64 tree.

This tree:

  http://git.et.redhat.com/?p=linux-2.6-fedora-pvops.git

is what we're actually shipping for F-9. It includes the x86_64 work,
but some other paravirt_ops patches too, most of which are queued up
upstream.

Cheers,
Mark.
