IRIX was assembling its TLB exception handler from a few such skeletons
or rather a few fractions. That works reasonably well as long as there are
not too many variants - but Linux supports about anything on earth.
Another disadvantage of the IRIX approach was that the fragments are
written in assembler but the tacking together happens in C code so the
code is split in a somewhat unnatural way over a few files.
