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.

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.
