The kernel will always (and must) create PTEs for all VM
spaces,   It's our choice to not use them.  In the case of Pinned
entries, what is supposed to happen is we load an entry that
covers a large space.  Since we never get a miss fault, we
never look at the PTE tables to load something different.

Thanks.
