Re: [PATCH V7 1/2] dma-mapping: Rework dma_get_cache_alignment()

All the other mips generic dma helpers are prefixed mips_dma_*
so it might make sense to follow that.

Also please don't add arch-local helpers to asm/dma-mapping.h - this
is a header used by linux/dma-mapping.h and should not contain
implementation details if avoidable.

> + dma_get_cache_alignment(NULL)) / mdev->limits.mtt_seg_size;

As said before - please don't pass NULL to this function but the proper
device, which would be &mdev->pdev->dev in this case for example.
