Re: [PATCH RFC v9 47/51] iommu/amd: Add IOMMU_SNP_SHUTDOWN support

[Suthikulpanit, Suravee]

FYI, you might need to start including the change from this patch

https://lore.kernel.org/linux-iommu/ZPiAUx9Qysw0AKNq@xxxxxxxx/T/

in this series since Christoph would like to remove the code from the 
current upstream, and re-introduce the change within this series instead.
