For reasons mentioned in the commit message, this happens to not be triggerable today, but is fragile, and could rear it's ugly head if a struct layout changes due to other backports in the future. [Test Case] Regression-only. [Fix] 84a9a75774961 iommu/arm-smmu-v3: Avoid memory corruption from Hisilicon MSI payloads [Regression Risk] The fix is to add some explicit padding into an internal structure. This padding is already implicit today.
