[Impact]

To properly support instance types in AWS with > 255 cores we need to make sure that commit c40aaaac1018ff1382f2d35df5129a6bcea3df6b ("iommu/vt-d: Gracefully handle DMAR units with no supported address widths") is applied across all our linux-aws kernels.

[Test Case]

Tests performed by AWS.

[Fix]

Apply/backport commit c40aaaac1018ff1382f2d35df5129a6bcea3df6b.

[Regression potential]

The fix is affecting only intel IOMMU and it is an upstream fix, so the regression potential is minimal.
