This adds support for multiple DMA address spaces per (PCI-)device. The use-case is to multiplex devices between host and KVM guests in a more flexible way than supported by SR-IOV. - the rest are smaller cleanups and fixes, two of which needed to be reverted after testing in linux-next. * tag 'iommu-updates-v5.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (45 commits) Revert "iommu/amd: Flush not present cache in iommu_map_page" Revert "iommu/amd: Remove the leftover of bypass support" iommu/vt-d: Fix leak in intel_pasid_alloc_table on error path iommu/vt-d: Make kernel parameter igfx_off work with vIOMMU iommu/vt-d: Set intel_iommu_gfx_mapped correctly iommu/amd: Flush not present cache in iommu_map_page iommu/vt-d: Cleanup: no spaces at the start of a line iommu/vt-d: Don't request page request irq under dmar_global_lock iommu/vt-d: Use struct_size() helper iommu/mediatek: Fix leaked of_node references iommu/amd: Remove amd_iommu_pd_list iommu/arm-smmu: Log CBFRSYNRA register on context fault iommu/arm-smmu-v3: Don't disable SMMU in kdump kernel iommu/arm-smmu-v3: Disable tagged pointers iommu/arm-smmu-v3: Add support for PCI ATS iommu/arm-smmu-v3: Link domains and devices iommu/arm-smmu-v3: Add a master->domain pointer iommu/arm-smmu-v3: Store SteamIDs in master iommu/arm-smmu-v3: Rename arm_smmu_master_data to arm_smmu_master ACPI/IORT: Check ATS capability in root complex nodes ... 2019-05-06T21:02:47Z Srinath Mannam srinath.mannam@broadcom.com 2019-05-03T14:05:32Z urn:sha1:e80a91ad302b3b66822756afc61f9f9c1658b9c9 Add a dma_ranges field in PCI host bridge structure to hold resource entries list of memory regions in sorted order representing memory ranges that can be accessed through DMA transactions.

Since we're about to use them in the Arm SMMUv3 driver, which could be built with CONFIG_PCI disabled, and they are already guarded by CONFIG_PCI_ATS which depends on CONFIG_PCI, move the definitions outside of CONFIG_PCI.

It never had an in tree user since then, so after 11 years later let's remove it. Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
