From a really far from sufficiently thorough look at linux, it looks
like it might be equivalent to putting stuff that is directly accessed
within [pmap_pa_start,pmap_pa_end) and having magic to map it to
And we can decide for domU that some stuff points to a dummy page and
so HYPERVISOR_mmu_update doesn't fail for it.
