* USII-io-diagnosis:
*
* This diagnosis engine consumes the Psycho based IO UEs and CEs
* which are generated due to DMA Reads or Writes.
*
* When a UE is received it will generate the appropriate fault
* (defect.ultraSPARC-II.memory.nodiag). This is because we do not plan
* to currently add greater diagnosis capabilities for USII systems.
*
* When a CE is received we allow the legacy in kernel SERD do it's job
* and we just bump a counter here. The legacy SERD algorithm will print
* out a message and retire pages when the SERD threshold is reached.
