Did you read the docs of this function?  That's exactly what it's
supposed to do.  Here's what the library reference says:

  Maps a physical device (like a graphics buffer) to linear memory.  Fill
  in the physical address and size (in bytes).  On return, the address is
  the linear address to use.
