This patch looks wrong to me.  It shouldn't replace __ia64_mf_a() with
platform_mmiob() because this will force the use of mf.a even on
platforms that don't need it for memory-mapped I/O.  Also, how about a
comment explaining exactly what is being ordered with respect to whom
(yes, I know there are many examples in Linux where this hasn't been
done, but I don't think that's a good reason to make the situation
worse).

Thanks,
