/*
 * The exception table consists of pairs of addresses: the first is the
 * address of an instruction that is allowed to fault, and the second is
 * the address at which the program should continue.  No registers are
 * modified, so it is entirely up to the continuation code to figure out
 * what to do.
 *
 * The nice thing about this mechanism is that the fixup code is completely
 * out of line with the main instruction path.  This means when everything
 * is well, we don't even have to jump over them.  Further, they do not intrude
 * on our cache or tlb entries.
