+ * 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).
+ *
+ * *mb() variants without smp_ prefix must order all types of memory
+ * operations with one another. sync is the only instruction sufficient
+ * to do this.
+ *
+ * For the smp_ barriers, ordering is for cacheable memory operations
+ * only. We have to use the sync instruction for smp_mb(), since lwsync
+ * doesn't order loads with respect to previous stores.  Lwsync can be
+ * used for smp_rmb() and smp_wmb().
+ *
+ * However, on CPUs that don't support lwsync, lwsync actually maps to a
+ * heavy-weight sync, so smp_wmb() can be a lighter-weight eieio.

- * Memory barrier.
- * The sync instruction guarantees that all memory accesses initiated

- * 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).
- *
- * *mb() variants without smp_ prefix must order all types of memory
- * operations with one another. sync is the only instruction sufficient
- * to do this.
- *
- * For the smp_ barriers, ordering is for cacheable memory operations
- * only. We have to use the sync instruction for smp_mb(), since lwsync
- * doesn't order loads with respect to previous stores.  Lwsync can be
- * used for smp_rmb() and smp_wmb().
- *
- * However, on CPUs that don't support lwsync, lwsync actually maps to a
- * heavy-weight sync, so smp_wmb() can be a lighter-weight eieio.
