/*  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
