* The MAU chip of the Niagara processor is not directly accessible

*
* The interfaces defines a queue of MAU operations to perform.
* Privileged code registers a queue with the hypervisor by invoking
* this HVAPI with the HV_NCS_QCONF sub-function, which defines the
* base, end, and number of entries of the queue. Each queue entry
* contains a MAU register struct block.
*
* The privileged code then proceeds to add entries to the queue and
* then invoke the HV_NCS_QTAIL_UPDATE sub-function. Since only
* synchronous operations are supported by the current hypervisor,
* HV_NCS_QTAIL_UPDATE will run all the pending queue entries to
* completion and return HV_EOK, or return an error code.
*
* The real address of the sub-function argument must be aligned on at
* least an 8-byte boundary.
*
* The tail argument of HV_NCS_QTAIL_UPDATE is an index, not a byte
* offset, into the queue and must be less than or equal the 'num_ents'
* argument given in the HV_NCS_QCONF call.
