+ * CPU-local atomic operations.
+ *
+ * The latomic module provides operations that are "atomic on the local
+ * processor", i.e. interrupt-safe. Its interface is similar in spirit
+ * and purpose to that of the atomic module, and it can transparently
+ * replace it on single-processor configurations.
+ *
+ * Note that the only operations guaranteed to be truely atomic, i.e.
+ * to completely execute in a single atomic instruction, are loads and
+ * stores. All other operations may be implemented with multiple
+ * instructions, possibly disabling interrupts. The rationale is that
+ * atomic loads and stores are required for some types of access, such
+ * as memory-mapped device registers, while other operations only require
+ * interrupt safety.
+ *
+ * This header provides a generic implementation. Architectures can
+ * individually override any of the operations provided by this module.
