[RFC 0/6] RISC-V IOMMU HPM and nested IOMMU support

[RFC 0/6] RISC-V IOMMU HPM and nested IOMMU support

[Zong Li]

This series includes RISC-V IOMMU hardware performance monitor and
nested IOMMU support. It also introduces operations for the g-stage
table, which are required for nested IOMMU.

This patch set is implemented on top of the RISC-V IOMMU v4 series [1],
and it will be submitted as an RFC until the RISC-V IOMMU has been
merged. Additionally, it will be updated as needed when a new version
of the RISC-V IOMMU series is posted.

Please drop this one, I have resent this series by removing the
'--thread=shadow' option from format-patch, as it causes RFC 5322
compliance issues, and also correct the subject of the series.
Thanks.
