  "message": "dma-debug: New interfaces to debug dma mapping errors\n\nAdd dma-debug interface debug_dma_mapping_error() to debug\ndrivers that fail to check dma mapping errors on addresses\nreturned by dma_map_single() and dma_map_page() interfaces.\nThis interface clears a flag set by debug_dma_map_page() to\nindicate that dma_mapping_error() has been called by the\ndriver. When driver does unmap, debug_dma_unmap() checks the\nflag and if this flag is still set, prints warning message\nthat includes call trace that leads up to the unmap. This\ninterface can be called from dma_mapping_error() routines to\nenable dma mapping error check debugging.\n\nTested: Intel iommu and swiotlb (iommu\u003dsoft) on x86-64 with\n        CONFIG_DMA_API_DEBUG enabled and disabled.\n\nSigned-off-by: Shuah Khan \u003cshuah.khan@hp.com\u003e\nReviewed-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nSigned-off-by: Joerg Roedel \u003cjoerg.roedel@amd.com\u003e\n",
