Hi Jacob,

This has been queued for internal test. I will forward it to Joerg if
everything goes well (probably around rc4).

Best regards,

Hi Joerg and Baolu,

Any more comments on this series? I rebased it on v5.5-rc1 without
changes.


Thanks,

Mostly extracted from nested SVA/SVM series based on review comments

This series also adds a few important fixes for native use of SVA.
Nested SVA new code will be submitted separately as a smaller set.
Based on the core branch of IOMMU tree staged for v5.5, where common
APIs for vSVA were applied.
