I analyzed all calls to dma_map_single() and dma_map_page() in the kernel, to see if callers check for mapping errors, before using the returned address.
The goal of this analysis is to find drivers that currently do not check dma mapping errors, and fix them. I documented the results of this analysis: http://linuxdriverproject.org/mediawiki/index.php/DMA_Mapping_Error_Analysis Please review and give me feedback on the analysis and the proposed next steps.
