Subject: [PATCH 0/3] iommu/vt-d: Global PASID name space

Hi,

This patch series is trying to change the scope of PASID management
used in Intel IOMMU driver from per IOMMU to driver global. This is
required for some cases where current per-IOMMU PASID name space
doesn't work. For an example, one application (associated with one
PASID) might talk to two physical devices simultaneously where two
devices could reside behind two different IOMMU units.

Best regards,
Lu Baolu
