Merge tag 'iommu-fixes-v5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel: - Fix a bug in the AMD IOMMU driver not handling exclusion ranges correctly. In fact the driver did not reserve these ranges for IOVA allocations, so that dma-handles could be allocated in an exclusion range, leading to data corruption. Exclusion ranges have not been used by any firmware up to now, so this issue remained undiscovered for quite some time. - Fix wrong warning messages that the IOMMU core code prints when it tries to allocate the default domain for an iommu group and the driver does not support any of the default domain types (like Intel VT-d). * tag 'iommu-fixes-v5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Reserve exclusion range in iova-domain iommu: Don't print warning when IOMMU driver only supports unmanaged domains
