7 * the address at which the program should continue. No registers are

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.
