IOMMU Fixes for Linux v4.14-rc4
Three fixes:
- Keep an important data structure in the Exynos driver around
after kernel-init to fix a kernel-oops
- Keep SWIOTLB enabled when SME is active in the AMD IOMMU
driver
- Add a missing IOTLB sync to the AMD IOMMU driver
iommu/amd: Finish TLB flush in amd_iommu_unmap()
The function only sends the flush command to the IOMMU(s),
but does not wait for its completion when it returns. Fix
that.
