Merge tag 'iommu-updates-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull IOMMU updates from Joerg Roedel:
 "Nothing big this time. In particular:

   - Debugging code for Tegra-GART

   - Improvement in Intel VT-d fault printing to prevent soft-lockups
     when on fault storms

   - Improvements in AMD IOMMU event reporting

   - NUMA aware allocation in io-pgtable code for ARM

   - Various other small fixes and cleanups all over the place"
