Xen will automatically infer the type when you attach an L1 to an
existing L2. Xen will infer the L2 type when the L2 gets used as
current pagetable base.
There are also mmu_op calls to pin a page to L1 or L2 type. This is
particularly important for L2 pages to get good performance.
Before a page has pagetable type you can have a writable mapping of it
and initiaqlise it directly. When Xen infers the pagetable type or you
pin it to such a type, you must already have relinuqished and writable
mappings you had of that page.
