History
Christoph Hellwig fec777c385 x86/dma: Use DMA-direct (CONFIG_DMA_DIRECT_OPS=y) 
The generic DMA-direct (CONFIG_DMA_DIRECT_OPS=y) implementation is now
functionally equivalent to the x86 nommu dma_map implementation, so
switch over to using it.

That includes switching from using x86_dma_supported in various IOMMU
drivers to use dma_direct_supported instead, which provides the same
functionality.
