* The exception table consists of pairs of addresses: the first is the
|
||
|
|
* address of an instruction that is allowed to fault, and the second is
|
||
|
|
* the address 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.
