/*

|
* 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.
