The IOMMU driver calculates the guest addressability for a DMA request
based on the value of the mgaw reported from the IOMMU. However, this
is a fused value and as mentioned in the spec, the guest width
should be calculated based on the minimum of supported adjusted guest
address width (SAGAW) and

Hi Greg,
This patch fixes an issue with the IOMMU driver and it only applies to 5.4,
4.19, and 4.14 stable kernels. May I know when this patch would be available in
the stable kernels?
Subject: iommu/vt-d: Fix agaw for a supported 48 bit guest address width
Thanks,
Saeed
