I suggested before:

"If dom0, enable >512G.
If domU, enable >512G if requested by command line option /or/ toolstack
indicates that it supports the linear p2m."

So this flag is only required to /automatically/ enable >512GB PV
guests.  You still need the manual (command line) override so this flag
isn't needed until the toolstack actually supports the linear p2m, and
the kernel support for this automatic enablement can be added later as well.
