Log message:
Support for non-exec mappings on sun4m.

- support exec traps and deal with them correctly.
- Instead of pretending that the pte permissions are a bit-mask, just
make two stupid 8-entry tables (one for kernel, one for userland) that
provides translation between VM_PROT* masks and pte permissions.

This gives sun4m a non-exec stack.
