Looks like there hasn't been much interest in reworking this to make stable backporting easier. I can apply patch 1 to the dma-mapping tree if that's still the plan, but for the other patches I'd need ACKs from the other maintainers.

I can queue 1 up in the dma-mapping tree, and if I get reviews for the mips and scsi bits I'd be happy to queue those up as well. But I think you'd be better off moving patches 3 and 4 to the front without the dma_get_cache_alignment prototype change so that they can be merged to stable.

2017-10-23 Thread Huacai Chen
Make dma_get_cache_alignment() to accept a 'dev' argument. As a result, it can return different alignments due to different devices' I/O cache coherency. Currently, ARM/ARM64 and MIPS support coherent & noncoherent devices co-exist. This may be extended in the future, so add a new function pointer
