Merge tag 'iommu-updates-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU updates from Joerg Roedel: "This pull-request includes: - change in the IOMMU-API to convert the former iommu_domain_capable function to just iommu_capable - various fixes in handling RMRR ranges for the VT-d driver (one fix requires a device driver core change which was acked by Greg KH) - the AMD IOMMU driver now assigns and deassigns complete alias groups to fix issues with devices using the wrong PCI request-id - MMU-401 support for the ARM SMMU driver - multi-master IOMMU group support for the ARM SMMU driver - various other small fixes all over the place" * tag 'iommu-updates-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (41 commits) iommu/vt-d: Work around broken RMRR firmware entries iommu/vt-d: Store bus information in RMRR PCI device path iommu/vt-d: Only remove domain when device is removed driver core: Add BUS_NOTIFY_REMOVED_DEVICE event iommu/amd: Fix devid mapping for ivrs_ioapic override iommu/irq_remapping: Fix the regression of hpet irq remapping iommu: Fix bus notifier breakage iommu/amd: Split init_iommu_group() from iommu_init_device() iommu: Rework iommu_group_get_for_pci_dev() iommu: Make of_device_id array const amd_iommu: do not dereference a NULL pointer address. iommu/omap: Remove omap_iommu unused owner field iommu: Remove iommu_domain_has_cap() API function IB/usnic: Convert to use new iommu_capable() API function vfio: Convert to use new iommu_capable() API function kvm: iommu: Convert to use new iommu_capable() API function iommu/tegra: Convert to iommu_capable() API function iommu/msm: Convert to iommu_capable() API function iommu/vt-d: Convert to iommu_capable() API function iommu/fsl: Convert to iommu_capable() API function ...
