I don't understand how it makes a difference. If the physical is
linear we don't care if it is THP or just a lucky list of 4k pages?
Agree, once we are fine with enabling THP or lucky list of 4k there is
no need for the VMA extra checking to force persistent huge pages.
In V1 will cleaned-up the VMA part from the patch and adapt the commit
