dma_mapping.h stubs

I am trying to build a kernel with support for SL811, but I am having trouble defining the stubs for dma_mapping.h I have checked the other threads in this forum, but there are no explicit exam...

Yes clansdown, they will be in the next release.

Hi sfielding, yes I mean asm-nios2nommu/dma-mapping.h. Please add the following to the beginning of the file: 

#include <asm/scatterlist.h># include <linux/mm.h># include <asm/io.h># include <asm/cacheflush.h>

You also need to add the following line to the file cacheflush.h in the same directory: 

extern void cache_clear (unsigned long paddr, int len);
