This is the correct thing to do ... but I wonder how we can validate
that there are no callers that were depending on the extra ordering
that the old volatile versions were providing.  Clearly any such callers
are broken ... but finding them the hard way (by executing the kernel
and waiting to see if something stange happens) is going to be unpleasant.
