     45  * NOTE: We must have all possible m68k kcore types defined in this
     46  * file.  Otherwise, we require kernel sources for all m68k platforms
     47  * to build userland.
     48  *
     49  * We must provide STE/PTE bits in the kcore header for a couple
     50  * of reasons:
     51  *
     52  *	- different platforms may have the MMUs configured for different
     53  *	  page sizes
     54  *	- we may not have a specific platform's pte.h available to us
     55  *
     56  * These are on-disk structures; use fixed-sized types!
     57  *
     58  * The total size of the cpu_kcore_hdr should be <= DEV_BSIZE!
