So 64 bit mode is like a Dataspace
The immediate problem addressed by amode 64 was to move data above
the bar. Hence the current similarity to dataspaces. However, the
architecture supports 64 bit execution; the problem is that the
operating system doesn't. As Chris Craddock pointed out, many of the
control blocks used to manage execution (and recovery) need to be
changed to support execution above the bar. It's still a work in
progress.
