- * The exception table consists of pairs of relative offsets: the first
- * is the relative offset to an instruction that is allowed to fault,
- * and the second is the relative offset 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.
- *
- * All the routines below use bits of fixup code that are 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.
