   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.

  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.
