+Subject: [PATCH] memory: Add IOMMU_ATTR_MSI_TRANSLATE IOMMU memory region
+ attribute
+
+We introduce a new IOMMU Memory Region attribute, IOMMU_ATTR_MSI_TRANSLATE
+which tells whether the virtual IOMMU translates MSIs. ARM SMMU
+will expose this attribute since, as opposed to Intel DMAR, MSIs
+are translated as any other DMA requests.
