- * Memory barrier.
- * The sync instruction guarantees that all memory accesses initiated
- * by this processor have been performed (with respect to all other
- * mechanisms that access memory).  The eieio instruction is a barrier
- * providing an ordering (separately) for (a) cacheable stores and (b)
- * loads and stores to non-cacheable memory (e.g. I/O devices).
- *
- * mb() prevents loads and stores being reordered across this point.
- * rmb() prevents loads being reordered across this point.
- * wmb() prevents stores being reordered across this point.
- * read_barrier_depends() prevents data-dependent loads being reordered
- *	across this point (nop on PPC).
- *
- * We have to use the sync instructions for mb(), since lwsync doesn't
- * order loads with respect to previous stores.  Lwsync is fine for
- * rmb(), though.
- * For wmb(), we use sync since wmb is used in drivers to order
- * stores to system memory with respect to writes to the device.
- * However, smp_wmb() can be a lighter-weight eieio barrier on
- * SMP since it is only used to order updates to system memory.
