I read the question. And I tried to answer.
 
No changes for 64 bit OS 64 bit apps - and that includes VMS.
 
(excluding boot process, which need to do some stuff before
it actually becomes a running 64 bit OS)
 
The details about why has been mentioned a few times
previously.
 
x86-64 in long mode only support 2 modes in PTE's, so
VMS x86-64 is a hardware 2 mode OS 4 mode OS - U in ring 3,
S, E and K in ring 0.

So in reality, user space and kernel space. That's a bit crap, tbh,
there are times where drivers, kernel code and user space could use a
bit of hardware separation.
