Patch from Jiri Gaisler <jgais@ce.chalmers.se>:
getting the spurious trap handling to work required a couple more
fixes - I have attached a patch against rtems-4.0.0 with the
necessary changes. I also added functionality so that the
address of the trapped instruction is reported and in case of
a data access error, the data address is also reported.
