[PATCH] dma-debug: Add dma map/unmap error tracking support

2012-09-02 Thread Shuah Khan
A recent dma mapping error analysis effort showed that a large precentage of dma_map_single() and dma_map_page() returns are not checked for mapping errors. Reference: https://lkml.org/lkml/2012/8/10/326 Adding support for tracking dma mapping and unmapping errors to help assess the following: Wh
