Message:

NVMe: Add support for the controller memory buffer (CMB) feature from the 1.2 NVMe spec. This can reduce some overhead compared to using PDMDevHlpPCIPhys{Read|Write} exclusively (which requires the PGM lock) when the guest decides to use it (Linux makes use of it for the I/O submission queues at this point)
