Renamed shm.h to shm_driver.h to avoid conflicts with POSIX shm.h.
Renamed file shmsupp/intr.c in some BSPs to shmsupp/cause_intr.c to
avoid conflict with rtems/src/intr.c (Classic API Interrupt Manager).

3 | * This routine is the shared memory driver routine which |
---|
4 | * generates interrupts to other CPUs. |
---|
5 | * |
---|
6 | * It uses the information placed in the node status control |
---|
7 | * block by each node. For example, when used with the Motorola |
---|
8 | * MVME136 board, the MPCSR is used. |
---|
9 | * |
---|
10 | * Input parameters: |
---|
11 | * node - destination of this packet (0 = broadcast) |
---|
12 | * |
---|
13 | * Output parameters: NONE |
