ISSUE: 

Issues since NWPA.NLM 3.07a (shipping code for NW51SP3)
NWPA.NLM
1) Handled the deadly embrace problem in ElevatorFilterAbort.  This fixed the
CPU hog Abend.
2) Changed all the aborts to use atomic xchg when setting the abort status, and
resetting if already completed. This fixed a multi-processor race condition
where we were setting message to aborted when they were being completed on
another processor. This resulted in an Abend where a HACB was executed while in
the wrong state.
3) Fixed adapterid in DeviceSpecificInfo if there is no adapter.
4) Fixed the Abend in CDI_Unbind_CDM_From_Object.
5) Fixed some command link displays.
6) Added device IO statistics.
7) Fixed nextmessage issues in the elevator.
8) Changed low priority requests from getting onto the nextmessage list.
9) Added "Long SCSI Command" support.
10) Added command line support to turn off autoloading of CDMs
11) Fixed a problem when the sector size changes on the media.

MM.NLM
1) Fixed a possible ABEND in HJ_Request code.
