Merge tag 'iommu-fixes-v4.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull IOMMU fixes from Joerg Roedel:
- fix a scheduling-while-atomic bug in the AMD IOMMU driver. It was
found after the checker was enabled earlier.
- a fix for the virtual APIC code in the AMD IOMMU driver which
delivers device interrupts directly into KVM guests for assigned
devices.
- fixes for the recently merged lock-less page-table code for ARM. The
redundant TLB syncs got reverted and locks added again around the TLB
sync code.
- fix for error handling in arm_smmu_add_device()
- address sanitization fix for arm io-pgtable code
