There was a frequently occurring pattern of "map this physical address into kernel VM, then read from it, then unmap it again". This new typed_map() encapsulates that logic by giving you back a typed pointer to the kind of structure you're interested in accessing. It returns a TypedMapping<T> that can be used mostly like a pointer. When destroyed, the TypedMapping object will unmap the memory. :^)
