Merge tag 'iommu-updates-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "This time there are not a lot of changes coming from the IOMMU side. That is partly because I returned from my parental leave late in the development process and probably partly because everyone was busy with Spectre and Meltdown mitigation work and didn't find the time for IOMMU work. So here are the few changes that queued up for this merge window: - 5-level page-table support for the Intel IOMMU. - error reporting improvements for the AMD IOMMU driver - additional DT bindings for ipmmu-vmsa (Renesas) - small fixes and cleanups" * tag 'iommu-updates-v4.16' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu: Clean up of_iommu_init_fn iommu/ipmmu-vmsa: Remove redundant of_iommu_init_fn hook iommu/msm: Claim bus ops on probe iommu/vt-d: Enable 5-level paging mode in the PASID entry iommu/vt-d: Add a check for 5-level paging support iommu/vt-d: Add a check for 1GB page support iommu/vt-d: Enable upto 57 bits of domain address width iommu/vt-d: Use domain instead of cache fetching iommu/exynos: Don't unconditionally steal bus ops iommu/omap: Fix debugfs_create_*() usage iommu/vt-d: clean up pr_irq if request_threaded_irq fails iommu: Check the result of iommu_group_get() for NULL iommu/ipmmu-vmsa: Add r8a779(70|95) DT bindings iommu/ipmmu-vmsa: Add r8a7796 DT binding iommu/amd: Set the device table entry PPR bit for IOMMU V2 devices iommu/amd - Record more information about unknown events
