3 *  This routine initializes, if necessary, and returns a pointer
4 *  to the Shared Memory Configuration Table for the XXX target.

6 *  INPUT PARAMETERS:
7 *    localnode - local node number
8 *    shmcfg    - address of pointer to SHM Config Table
9 *
10 *  OUTPUT PARAMETERS:
11 *    *shmcfg   - pointer to SHM Config Table
12 *
13XXX: FIX THE COMMENTS BELOW WHEN THE CPU IS KNOWN
14 *  NOTES:  The XYZ does not have an interprocessor interrupt.
