- read/write/execute permissions in a simple enough way to fit entirely into the
- 64-entry TLB cache.
-
- This code does not do address relocation and does not generate any MMU-related interrupts.
-
- The process ID support is there for a possible future extension where RTEMS supports
- setting the process ID on task switches, which allows per-process stack protection
-
- This code will call fatal_error() if your add_space() calls overrun the 64 entries
