Merge branches 'iommu/arm/smmu', 'iommu/updates', 'iommu/vt-d', 'iommu/ipmmu-vmsa' and 'iommu/iova' into iommu-next-20171113.0 (2017-11-13 12:40:51 -0700)

----------------------------------------------------------------

IOMMU Updates for Linux v4.15

* Enforce MSI multiple IRQ alignment in AMD IOMMU

* VT-d PASID error handling fixes

* Add r8a7795 IPMMU support

* Manage runtime PM links on exynos at {add,remove}_device callbacks

* Fix Mediatek driver name to avoid conflict

* Add terminate support to qcom fault handler

* 64-bit IOVA optimizations

* Simplfy IOVA domain destruction, better use of rcache, and
skip anchor nodes on copy

* Convert to IOMMU TLB sync API in io-pgtable-arm{-v7s}

* Drop command queue lock when waiting for CMD_SYNC completion on
ARM SMMU implementations supporting MSI to cacheable memory

* iomu-vmsa cleanup inspired by missed IOTLB sync callbacks

* Fix sleeping lock with preemption disabled for RT

* Dual MMU support for TI DRA7xx DSPs

* Optional flush option on IOVA allocation avoiding overhead when
caller can try other options
