The exception and interrupt handling are two completely different things here.
On PowerPC the external exception (among other types) handler code resides in
c/src/lib/libcpu/powerpc/new-exceptions. Here are the prologues and epilogues
that deal with the different exception types.  The interrupt support stuff in
c/src/lib/libbsp/shared deals with the specific interrupt sources that cause an
external exception.
