[GIT PULL] dma-mapping updates for Linux 4.16

Hi Linus, below is the update for the dma-mapping subsystem for Linux 4.16. Except for a runtime warning fix from Christian this is all about consolidating the direct mapping and swiotlb dma maps based on the x86 code, which will hopefully be switched to this generic code as well in the next

[PATCH v3] iommu/amd: Add support for fast IOTLB flushing

Implement the newly added IOTLB flushing interface for AMD IOMMU. Cc: Joerg Roedel Signed-off-by: Suravee Suthikulpanit --- Changes from v2 (https://lkml.org/lkml/2017/12/27/44) * Call domain_flush_complete() after domain_flush_tlb_pde().

[PATCH 0/2] iommu / vfio: Clean up iommu_map[_fast] interface

Change iommu_unmap[_fast] interfaces return type to ssize_t since it can also return error code. Cc: Joerg Roedel Cc: Alex Williamson Suravee Suthikulpanit (2): iommu: Fix iommu_unmap and iommu_unmap_fast return type vfio/type1: Add iommu_unmap

[PATCH 1/2] iommu: Fix iommu_unmap and iommu_unmap_fast return type

Currently, iommu_unmap and iommu_unmap_fast return unmapped pages with size_t. However, the actual value returned could be error codes (< 0), which can be misinterpreted as large number of unmapped pages. Therefore, change the return type to ssize_t. Cc: Joerg Roedel Cc: Alex

[PATCH 2/2] vfio/type1: Add iommu_unmap error check when vfio_unmap_unpin

Besides zero check the number of unmapped page, also check and handle iommu_unmap errors. Cc: Alex Williamson Cc: Joerg Roedel Signed-off-by: Suravee Suthikulpanit --- drivers/vfio/vfio_iommu_type1.c | 5 +++-- 1 file
