We want to have only a single pagetable walker and reuse the same functionality for vmemmap handling. Let's start by consolidating vmem_add_range() and vmem_remove_range(), converting it into a recursive implementation. A recursive implementation makes it easier to expand individual cases without harming readability. In addition, we minimize traversing the whole hierarchy over and over again. One change is that we don't unmap large PMDs/PUDs when not completely covered by the request, something that should never happen with direct mappings, unless one would be removing in other granularity than added, which would be broken already.
