  38  * NOTE: We must have all possible m68k kcore types defined in this
  39  * file.  Otherwise, we require kernel sources for all m68k platforms
  40  * to build userland.
  41  *
  42  * We must provide STE/PTE bits in the kcore header for a couple
  43  * of reasons:
  44  *
  45  *      - different platforms may have the MMUs configured for different
  46  *        page sizes
  47  *      - we may not have a specific platform's pte.h available to us
  48  *
  49  * These are on-disk structures; use fixed-sized types!
  50  *
  51  * The total size of the cpu_kcore_hdr should be <= DEV_BSIZE!
