+/*  void Shm_Cause_interrupt( node )
+ *
+ *  This routine is the shared memory driver routine which
+ *  generates interrupts to other CPUs.
+ *
+ *  It uses the information placed in the node status control
+ *  block by each node.  For example, when used with the Motorola
+ *  MVME136 board, the MPCSR is used.
+ *
+ *  Input parameters:
+ *    node          - destination of this packet (0 = broadcast)
+ *
+ *  Output parameters: NONE
