| * 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. | |
