      5 * The exception table consists of pairs of addresses: the first is the
      6 * address of an instruction that is allowed to fault, and the second is
      7 * the address at which the program should continue.  No registers are
      8 * modified, so it is entirely up to the continuation code to figure out
      9 * what to do.
     10 *
     11 * All the routines below use bits of fixup code that are out of line
     12 * with the main instruction path.  This means when everything is well,
     13 * we don't even have to jump over them.  Further, they do not intrude
     14 * on our cache or tlb entries.
