Linus Torvalds e16c4790de Revert "iommu/amd_iommu: Use CONFIG_DMA_DIRECT_OPS=y and dma_direct_{alloc,free}()" 
This reverts commit b468620f2a.

It turns out that this broke drm on AMD platforms. Quoting Gabriel C:
 "I can confirm reverting b468620f2a fixes
  that issue for me.

  The GPU is working fine with SME enabled.

  Now with working GPU :) I can also confirm performance is back to
  normal without doing any other workarounds"

Christan König analyzed it partially:
 "As far as I analyzed it we now get an -ENOMEM from dma_alloc_attrs()
  in drivers/gpu/drm/ttm/ttm_page_alloc_dma.c when IOMMU is enabled"

and Christoph Hellwig responded:
 "I think the prime issue is that dma_direct_alloc respects the dma
  mask. Which we don't need if actually using the iommu. This would be
  mostly harmless exept for the the SEV bit high in the address that
  makes the checks fail.

  For now I'd say revert this commit for 4.17/4.18-rc and I'll look into
  addressing these issues properly"
