I agree in principle, although I am really not happy about the idea of
disallowing 64-bit writes from device drivers that haven't explicitly
indicated they won't support it.

However, I would *also* like if more drivers would explicitly specify
the transfer size they expect.  Right now, that is done though a set of
functions whose name are a bit of a mismatch to the others:
__iowrite{32,64}_copy(), which probably should be renamed
memcpy_toio{32,64}() and augmented with matching memcpy_fromio{32,64}()
functions.

What do you think?
