We've been creating the virtio-mmio devices in forwards order

the virtio busses end up with decreasing base address order.

This series breaks out parts of the ARM PVH support into an abstract

On the way towards Xen safety certification we're evaluating the use
of tools to collect code-coverage/profiling information from execution
traces. Some tools rely on ELF symbols for code being declared with
type FUNC and having a symbol size.
