This needs more of a description.  Also, for a single patch, it's silly
to send two mails, the first being a cover which has a little more
information in it about the patch than the patch itself.

You need to explain _why_ you're making this change.  What I want to see
is that you've thought about the implications of this - particularly that
you know that strongly ordered memory does *not* imply any ordering with
any other memory types.

In other words, I want to know that this change is not a bodge but there's
a real reason behind it.
