Description: Enable debugging of DMA-API usage

More info: 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 degradation. Use only if you want to debug device drivers and dma interactions. If unsure, say N.
