Merge branch 'pci/virtualization'
- Fix erroneous intel-iommu dependency on CONFIG_AMD_IOMMU (Bjorn
Helgaas)
- Move pci_prg_resp_pasid_required() to CONFIG_PCI_PRI (Bjorn Helgaas)
- Allow VFs to use PRI (the PF PRI is shared by the VFs, but the code
previously didn't recognize that) (Kuppuswamy Sathyanarayanan)
- Allow VFs to use PASID (the PF PASID capability is shared by the VFs,
but the code previously didn't recognize that) (Kuppuswamy
Sathyanarayanan)
- Disconnect PF and VF ATS enablement, since ATS in PFs and associated
VFs can be enabled independently (Kuppuswamy Sathyanarayanan)
- Cache PRI and PASID capability offsets (Kuppuswamy Sathyanarayanan)
- Cache the PRI PRG Response PASID Required bit (Bjorn Helgaas)
- Consolidate ATS declarations in linux/pci-ats.h (Krzysztof Wilczynski)
- Remove unused PRI and PASID stubs (Bjorn Helgaas)
- Removed unnecessary EXPORT_SYMBOL_GPL() from ATS, PRI, and PASID
interfaces that are only used by built-in IOMMU drivers (Bjorn Helgaas)
- Hide PRI and PASID state restoration functions used only inside the PCI
core (Bjorn Helgaas)
- Fix the UPDCR register address in the Intel ACS quirk (Steffen
Liebergeld)
- Add a DMA alias quirk for the Intel VCA NTB (Slawomir Pawlowski)
- Serialize sysfs sriov_numvfs reads vs writes (Pierre Crégut)
- Update Cavium ACS quirk for ThunderX2 and ThunderX3 (George Cherian)
- Unify ACS quirk implementations (Bjorn Helgaas)

PCI: Fix Intel ACS quirk UPDCR register address
PCI/ATS: Make pci_restore_pri_state(), pci_restore_pasid_state() private
PCI/ATS: Remove unnecessary EXPORT_SYMBOL_GPL()
PCI/ATS: Remove unused PRI and PASID stubs
PCI/ATS: Consolidate ATS declarations in linux/pci-ats.h
PCI/ATS: Cache PRI PRG Response PASID Required bit
PCI/ATS: Cache PASID Capability offset
PCI/ATS: Cache PRI Capability offset
PCI/ATS: Disable PF/VF ATS service independently
PCI/ATS: Handle sharing of PF PASID Capability with all VFs
PCI/ATS: Handle sharing of PF PRI Capability with all VFs
PCI/ATS: Move pci_prg_resp_pasid_required() to CONFIG_PCI_PRI
iommu/vt-d: Select PCI_PRI for INTEL_IOMMU_SVM
