Pull IOMMU updates from Joerg Roedel: "This time the updates contain: - Tracepoints for certain IOMMU-API functions to make their use easier to debug - A tracepoint for IOMMU page faults to make it easier to get them in user space - Updates and fixes for the new ARM SMMU driver after the first hardware showed up - Various other fixes and cleanups in other IOMMU drivers" * tag 'iommu-updates-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (26 commits) iommu/shmobile: Enable the driver on all ARM platforms iommu/tegra-smmu: Staticize tegra_smmu_pm_ops iommu/tegra-gart: Staticize tegra_gart_pm_ops iommu/vt-d: Use list_for_each_entry_safe() for dmar_domain->devices traversal iommu/vt-d: Use for_each_drhd_unit() instead of list_for_each_entry() iommu/vt-d: Fixed interaction of VFIO_IOMMU_MAP_DMA with IOMMU address limits iommu/arm-smmu: Clear global and context bank fault status registers iommu/arm-smmu: Print context fault information iommu/arm-smmu: Check for num_context_irqs > 0 to avoid divide by zero exception iommu/arm-smmu: Refine check for proper size of mapped region iommu/arm-smmu: Switch to subsys_initcall for driver registration iommu/arm-smmu: use relaxed accessors where possible iommu/arm-smmu: replace devm_request_and_ioremap by devm_ioremap_resource iommu: Remove stack trace from broken irq remapping warning iommu: Change iommu driver to call io_page_fault trace event iommu: Add iommu_error class event to iommu trace iommu/tegra: gart: cleanup devm_* functions usage iommu/tegra: Print phys_addr_t using %pa iommu: No need to pass '0x' when '%pa' is used iommu: Change iommu driver to call unmap trace event ...
