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
