Merge tag 'iommu-updates-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU upates from Joerg Roedel: "This time a few more updates queued up. - Rework VT-d code to support ACPI devices - Improvements for memory and PCI hotplug support in the VT-d driver - Device-tree support for OMAP IOMMU - Convert OMAP IOMMU to use devm_* interfaces - Fixed PASID support for AMD IOMMU - Other random cleanups and fixes for OMAP, ARM-SMMU and SHMOBILE IOMMU Most of the changes are in the VT-d driver because some rework was necessary for better hotplug and ACPI device support" * tag 'iommu-updates-v3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (75 commits) iommu/vt-d: Fix error handling in ANDD processing iommu/vt-d: returning free pointer in get_domain_for_dev() iommu/vt-d: Only call dmar_acpi_dev_scope_init() if DRHD units present iommu/vt-d: Check for NULL pointer in dmar_acpi_dev_scope_init() iommu/amd: Fix logic to determine and checking max PASID iommu/vt-d: Include ACPI devices in iommu=pt iommu/vt-d: Finally enable translation for non-PCI devices iommu/vt-d: Remove to_pci_dev() in intel_map_page() iommu/vt-d: Remove pdev from intel_iommu_attach_device() iommu/vt-d: Remove pdev from iommu_no_mapping() iommu/vt-d: Make domain_add_dev_info() take struct device iommu/vt-d: Make domain_remove_one_dev_info() take struct device iommu/vt-d: Rename 'hwdev' variables to 'dev' now that that's the norm iommu/vt-d: Remove some pointless to_pci_dev() calls iommu/vt-d: Make get_valid_domain_for_dev() take struct device iommu/vt-d: Make iommu_should_identity_map() take struct device iommu/vt-d: Handle RMRRs for non-PCI devices iommu/vt-d: Make get_domain_for_dev() take struct device iommu/vt-d: Make domain_context_mapp{ed,ing}() take struct device iommu/vt-d: Make device_to_iommu() cope with non-PCI devices ...
