 * You need to do them by hand if the operations depend on ordering.
 *
 * Similarly, the port IO operations do a "mb" only after a write operation:
 * if an mb is needed before (as in the case of doing memory mapped IO
 * first, and then a port IO operation to the same device), it needs to be
 * done by hand.
 *
 * After the above has bitten me 100 times, I'll give up and just do the
 * mb all the time, but right now I'm hoping this will work out.  Avoiding
 * mb's may potentially be a noticeable speed improvement, but I can't
 * honestly say I've tested it.
 *
 * Handling interrupts that need to do mb's to synchronize to non-interrupts
 * is another fun race area.  Don't do it (because if you do, I'll have to
 * do *everything* with interrupts disabled, ugh).
