5 * The exception table consists of pairs of relative offsets: the first
6 * is the relative offset to an instruction that is allowed to fault,
7 * and the second is the relative offset at which the program should
8 * continue. No registers are modified, so it is entirely up to the
9 * continuation code to figure out 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.
