Olliver, just note that I reduced a lot your initial patch in a sense to add
only what is close to the existing users, i.e. ioreadXX() and their atomic
versions (no be(), no _rep() variants). If you are objecting that, you need
to have yet another patch(es) to prove that there are users.

Also note, that I reordered macro appearance to be consistent with existing
schema.
