ChangeSet 1.2199.14.32, 2005/03/23 12:13:40-08:00, [EMAIL PROTECTED]
[CRYPTO]: Remap when walk_out crosses page in crypt()
This is needed so that we can keep the in_place assignment outside the
inner loop. Without this in pathalogical situations we can start out
having walk_out being different from walk_in, but when walk_out crosses
a page it may converge with walk_in.
