Subject: [PATCH v2 0/2] iommu/vt-d: pfsid fix

When device invalidation throttling(DIT) is supported by an IOMMU, device TLB
invalidation should include physical function source ID(PFSID).

Changes since v1:
- Fixed compile error when CONFIG_PCI_ATS is not set
- Simplified how PF source ID is retrieved

Jacob Pan (2):
  iommu/vt-d: add definitions for PFSID
  iommu/vt-d: fix dev iotlb pfsid use
