Merge tag 'iommu-updates-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "This time with: - A new IOMMU-API call: iommu_map_sg() to map multiple non-contiguous pages into an IO address space with only one API call. This allows certain optimizations in the IOMMU driver. - DMAR device hotplug in the Intel VT-d driver. It is now possible to hotplug the IOMMU itself. - A new IOMMU driver for the Rockchip ARM platform. - Couple of cleanups and improvements in the OMAP IOMMU driver. - Nesting support for the ARM-SMMU driver. - Various other small cleanups and improvements. Please note that this time some branches were also pulled into other trees, like the DRI and the Tegra tree. The VT-d branch was also pulled into tip/x86/apic. Some patches for the AMD IOMMUv2 driver are not in the IOMMU tree but were merged by Andrew (or finally ended up in the DRI tree)" * tag 'iommu-updates-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (42 commits) iommu: Decouple iommu_map_sg from CPU page size iommu/vt-d: Fix an off-by-one bug in __domain_mapping() pci, ACPI, iommu: Enhance pci_root to support DMAR device hotplug iommu/vt-d: Enhance intel-iommu driver to support DMAR unit hotplug iommu/vt-d: Enhance error recovery in function intel_enable_irq_remapping() iommu/vt-d: Enhance intel_irq_remapping driver to support DMAR unit hotplug iommu/vt-d: Search for ACPI _DSM method for DMAR hotplug iommu/vt-d: Implement DMAR unit hotplug framework iommu/vt-d: Dynamically allocate and free seq_id for DMAR units iommu/vt-d: Introduce helper function dmar_walk_resources() iommu/arm-smmu: add support for DOMAIN_ATTR_NESTING attribute iommu/arm-smmu: Play nice on non-ARM/SMMU systems iommu/amd: remove compiler warning due to IOMMU_CAP_NOEXEC iommu/arm-smmu: add IOMMU_CAP_NOEXEC to the ARM SMMU driver iommu: add capability IOMMU_CAP_NOEXEC iommu/arm-smmu: change IOMMU_EXEC to IOMMU_NOEXEC iommu/amd: Fix accounting of device_state x86/vt-d: Fix incorrect bit operations in setting values iommu/rockchip: Allow to compile with COMPILE_TEST iommu/ipmmu-vmsa: Return proper error if devm_request_irq fails ...
