- Make a UVM_OBJ_IS_DEVICE macro.
- Use it to skip device mappings while dumping core.
- Ignore EFAULT errors while dumping core since they can happen
even for valid mappings. Just skip that part of the core file and
let it get automagically zero-filled.
This fixes the broken X core dumps that people have been seeing and also
fixes some other potential problems that could prevent core dumps (mmaps
beyond EOF, etc.).
