Hi,

The "Optimizing iommu_[map/unmap] performance" series posted here,

https://lore.kernel.org/linux-iommu/1623850736-389584-1-git-send-email-quic_c_gdjako@quicinc.com/

improves the iommu_[map/unmap] performce by reducing the number of
calls to the vendor-specific map/unmap callbacks. This series
introduces the implementation of those new callbacks in Intel IOMMU
implementation.

Note: This series depends on above series. It can only be taken after
above series get merged.

Best regards,
baolu
