As far as I'm aware, no cpu that you can get ahold of support

There is simply no reason at this time to support more, due to
the fact that nobody has implemented anywhere near that maximum.
Also worth noting, the address a block of memory is, has no
relation to the hardware. A kernel will instruct the cpu to map
it wherever it pleases per process.
Thanks for the info. I'm surprised that kernel set virtual space
that high.
