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