Then how about your alternative, ARM specific solution, "Avoid aliasing 
mappings in DMA coherent allocator"? There was a series of initially 
two, then three patches, of which the two others (459c1517f987 "ARM: 
DMA: Replace page_to_dma()/dma_to_page() with pfn_to_dma()/dma_to_pfn()" 
and 9eedd96301ca "ARM: DMA: top-down allocation in DMA coherent region") 
are already in the mainline tree. I'm still porting a copy of that third 
one from kernel version to version to have my device working 100% 
reliably, in hope you finally push it into the mainline. No plans 
against it? Or is there something about it I could help with?

Thanks,
Janusz
