    sys/dev/drm          radeon_cp.c 
  Log:
  Mark the permanent map for radeon registers read-only.  Failure to set this flag
  allowed writing to the registers by any user that can open the DRI device, and
  therefore ability to initiate DMA.  This came in with the merge from DRI CVS on
  2005-04-15.
