* This is the protection domain doorbell register map. Note that

* accessing the doorbells to know which are valid. Each doorbell
* occupies 32 bytes of space, but unless otherwise specified,
* only the first 4 bytes should be written. There are 32 instances
* of these doorbells for the host and 31 virtual machines respectively.
* The host and VMs will only map the doorbell pages belonging to its
* protection domain. It will not be able to touch the doorbells for
* another VM. The doorbells are the only registers directly accessible
* by a virtual machine. Similarly, there are 511 additional
* doorbells for RDMA protection domains. PD 0 for RDMA shares
* the same physical protection domain doorbell page as ETH/iSCSI.
