Ok, let's see how it works out.
I think in the initial phase we should be conservative and should attempt to
introduce as few unrelated changes as possible, and get the conversion done.
The
current x86 entry code is a reasonable base to start with.
Once most of the 'mechanic' conversion is done we can do all the other changes.
The conversion itself is risky enough as-is, we want to offload as much of any
other risk to after the conversion is done.
Thanks,
Ingo
