Sorry for my stupid question.
It is not a stupid question.
Why the gpa -> hva mapping is not
consistent for RAM if -mempath is not used?
Video RAM in the range a0000-bffff and PCI mapped RAM can change gpas
(while remaining in the same hva).
Even for ordinary RAM, which doesn't normally change gpa/hva, I'm not
sure we want to guarantee that it won't.
