Traits and Structs to manage guest physical address space for virtual machines.
The vm-memory implements mechanisms to manage and access guest memory resident in guest physical address space. In addition to guest memory, there may be other type of devices resident in the same guest physical address space.
The dbs-address-space crate provides traits and structs to manage the guest physical address
space for virtual machines, and mechanisms to coordinate all the devices resident in the
guest physical address space.
