Linus Torvalds fb4e3beeff IOMMU Updates for Linux v4.13
This update comes with:
 
 	* Support for lockless operation in the ARM io-pgtable code.
 	  This is an important step to solve the scalability problems in
 	  the common dma-iommu code for ARM
 
 	* Some Errata workarounds for ARM SMMU implemenations
 
 	* Rewrite of the deferred IO/TLB flush code in the AMD IOMMU
 	  driver. The code suffered from very high flush rates, with the
 	  new implementation the flush rate is down to ~1% of what it
 	  was before
 
 	* Support for amd_iommu=off when booting with kexec. Problem
 	  here was that the IOMMU driver bailed out early without
 	  disabling the iommu hardware, if it was enabled in the old
 	  kernel
 
 	* The Rockchip IOMMU driver is now available on ARM64
 
 	* Align the return value of the iommu_ops->device_group
 	  call-backs to not miss error values
 
 	* Preempt-disable optimizations in the Intel VT-d and common
 	  IOVA code to help Linux-RT
 
 	* Various other small cleanups and fixes
