+	depends on HAVE_DMA_API_DEBUG
+	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.
