title: Can I map to memory the seekable character device `/dev/mem_8` and access to it by using x86_64 instructions?
body: <p>If I have a seekable character device - <code>/dev/mem_8</code>, allowing a user-space program random access to the memory array with simple I/O operations, can I map it to the virtual addressing memory of my process to ease access to it by using x86_64 instructions: <code>MOV</code>, <code>REP MOVS</code>, and SSE: <code>MOVNTDQ</code>, <code>MOVNTDQA</code> ... ?</p>
  
  <p>OS: Linux x86_64 kernel >= 2.6</p>
