[Xen-devel] EXPORT_SYMBOL

["Charles Coffing" <ccoffing@xxxxxxxxxx>]

I built 2.6.7-xen0 with modular drivers, but I couldn't get any modules
to load because the following symbols weren't exported:
        evtchn_do_upcall
        HYPERVISOR_shared_info
        phys_to_machine_mapping


Here's a patch:
