* mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
r46xx/vectorisrs/vectorisrs.c, tx39/vectorisrs/vectorisrs.c,
tx39/include/tx3904.h: All exceptions were given low numbers and thus
can be now be installed and processed in a uniform manner just like interrupts.
Variances between various MIPS ISA levels are not accounted for at this time.
* mongoosev/vectorisrs/Makefile.am, mongoosev/vectorisrs/maxvectors.c,
r46xx/vectorisrs/Makefile.am, r46xx/vectorisrs/maxvectors.c,
tx39/vectorisrs/Makefile.am, tx39/vectorisrs/maxvectors.c,
shared/interrupts/maxvectors.c, shared/interrupts/Makefile.am: Split the
shared maxvectors.c into a variety of CPU model specific versions to simplify
the build process and reduce depdencies. Deleted shared/interrupts/maxvectors.c
and created various CPU model versions.
