Please try it. The point there was that we have a problem in ep93xx VIC/DMA code but it is totally different thing and not related to Rafal's patch. We can sort the VIC thing out separately IMHO. ep93xx dma in 3.3 is broken regardless this patch.
I think, that we can't be 100% sure that these two problems are not related at all. If some changes to VIC/ep93xx interrupt handling etc will be send to list, I'll test them in my configuration without my patch. If it will help (to fix the problem I'm observing also in 3.2), then double buffering for M2M could be much simplier. Now, I'm trying to test mmc_spi in ep93xx and let you know what the results are.
