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