 +      help
 +        Enable this option to debug the use of the DMA API by device drivers.
 +        With this option you will be able to detect common bugs in device
 +        drivers like double-freeing of DMA mappings or freeing mappings that
 +        were never allocated.
 +        This option causes a performance degredation.  Use only if you want
 +        to debug device drivers. If unsure, say N.
