it would seem to me that the change to again allow cs/ds prefixes in
64-bit mode should be undone. If you want branch prediction hints, use
the ,ht and ,hn instruction suffixes. Using segment overrides in their
place is counter intuitive, and generally allowing them in 64-bit mode
is an error in any case (if you absolutely wanted to allow them for this
specific purpose, then you'd have to add checks in other places
preventing incorrect uses).

Thanks, Jan
