- * NOTE! The memory operations do not set any memory barriers, as it's
- * not needed for cases like a frame buffer that is essentially memory-like.
- * 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).
