- There is one other exception - debuggers that look at the U area, which
- includes both "adb" and "dbx", at least in their SunOS 4.1.1
- incarnation, are also potentially kernel-architecture-dependent, if the
- U area changes for different kernel architectures (e.g., by sticking a
- level 1 page table there on machines with in-memory page-table MMUs).
