Subject: [GIT PULL] IOMMU updates for v4.15
Hi Linus,
As Joerg mentioned[1], he's out on paternity leave through the end of
the year and I'm filling in for him in the interim. Thanks,
Alex

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
