Re: [PATCH V9 1/4] dma-mapping: Rework dma_get_cache_alignment()

[Christoph Hellwig]

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.
