|
|
* 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.
