    Yep, pretty much. They're all generally to do with Xen's virtual device
    model, and are needed by modular frontend/backed drivers. This series
    only includes the basic block and network frontend devices, but there
    are more waiting in the wings.

    The breakdown, roughly, is:

    * event channel management
    * pseudophysical <-> machine addresses
    * grant-table management
    * xenbus, which includes
    o which has a filesystem-like namespace
    o the means to monitor changes in objects in the namespace
    o shared resource management
    o suspend/resume
