Merge tag 'iommu-updates-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "The updates include: - Small code cleanups in the AMD IOMMUv2 driver - Scalability improvements for the DMA-API implementation of the AMD IOMMU driver. This is just a starting point, but already showed some good improvements in my tests. - Removal of the unused Renesas IPMMU/IPMMUI driver - Updates for ARM-SMMU include: * Some fixes to get the driver working nicely on Broadcom hardware * A change to the io-pgtable API to indicate the unit in which to flush (all callers converted, with Ack from Laurent) * Use of devm_* for allocating/freeing the SMMUv3 buffers - Some other small fixes and improvements for other drivers" * tag 'iommu-updates-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (46 commits) iommu/vt-d: Fix up error handling in alloc_iommu iommu/vt-d: Check the return value of iommu_device_create() iommu/amd: Remove an unneeded condition iommu/amd: Preallocate dma_ops apertures based on dma_mask iommu/amd: Use trylock to aquire bitmap_lock iommu/amd: Make dma_ops_domain->next_index percpu iommu/amd: Relax locking in dma_ops path iommu/amd: Initialize new aperture range before making it visible iommu/amd: Build io page-tables with cmpxchg64 iommu/amd: Allocate new aperture ranges in dma_ops_alloc_addresses iommu/amd: Optimize dma_ops_free_addresses iommu/amd: Remove need_flush from struct dma_ops_domain iommu/amd: Iterate over all aperture ranges in dma_ops_area_alloc iommu/amd: Flush iommu tlb in dma_ops_free_addresses iommu/amd: Rename dma_ops_domain->next_address to next_index iommu/amd: Remove 'start' parameter from dma_ops_area_alloc iommu/amd: Flush iommu tlb in dma_ops_aperture_alloc() iommu/amd: Retry address allocation within one aperture iommu/amd: Move aperture_range.offset to another cache-line iommu/amd: Add dma_ops_aperture_alloc() function ...
