+ * Unified m68k kcore header descriptions.
+ *
+ * NOTE: We must have all possible m68k kcore types defined in this
+ * file.  Otherwise, we require kernel sources for all m68k platforms
+ * to build userland.
+ *
+ * We must provide STE/PTE bits in the kcore header for a couple
+ * of reasons:
+ *
+ *     - different platforms may have the MMUs configured for different
+ *       page sizes
+ *     - we may not have a specific platform's pte.h available to us
+ *
+ * These are on-disk structures; use fixed-sized types!
+ *
+ * The total size of the cpu_kcore_hdr should be <= DEV_BSIZE!
