/*
- * Define __packed if someone hasn't beat us to it. Linux kernel style
- * checking prefers __packed over __attribute__((packed)).
+ * Attributes for EC request and response packets. Just defining __packed
+ * results in inefficient assembly code on ARM, if the structure is actually
+ * 32-bit aligned, as it should be for all buffers.
+ *
+ * Be very careful when adding these to existing structures. They will round
+ * up the structure size to the specified boundary.
+ *
+ * Also be very careful to make that if a structure is included in some other
+ * parent structure that the alignment will still be true given the packing of
+ * the parent structure. This is particularly important if the sub-structure
+ * will be passed as a pointer to another function, since that function will
+ * not know about the misaligment caused by the parent structure's packing.
+ *
+ * Also be very careful using __packed - particularly when nesting non-packed
+ * structures inside packed ones. In fact, DO NOT use __packed directly;
+ * always use one of these attributes.
+ *
+ * Once everything is annotated properly, the following search strings should
+ * not return ANY matches in this file other than right here:
+ *
+ * "__packed" - generates inefficient code; all sub-structs must also be packed
+ *
+ * "struct [^_]" - all structs should be annotated, except for structs that are
+ * members of other structs/unions (and their original declarations should be
+ * annotated).
