Linus Torvalds 4f9701057a IOMMU Updates for Linux v5.13
Including:
 
 	- Big cleanup of almost unsused parts of the IOMMU API by
 	  Christoph Hellwig. This mostly affects the Freescale PAMU
 	  driver.
 
 	- New IOMMU driver for Unisoc SOCs
 
 	- ARM SMMU Updates from Will:
 
 	  - SMMUv3: Drop vestigial PREFETCH_ADDR support
 	  - SMMUv3: Elide TLB sync logic for empty gather
 	  - SMMUv3: Fix "Service Failure Mode" handling
     	  - SMMUv2: New Qualcomm compatible string
 
 	- Removal of the AMD IOMMU performance counter writeable check
 	  on AMD. It caused long boot delays on some machines and is
 	  only needed to work around an errata on some older (possibly
 	  pre-production) chips. If someone is still hit by this
 	  hardware issue anyway the performance counters will just
 	  return 0.
 
 	- Support for targeted invalidations in the AMD IOMMU driver.
 	  Before that the driver only invalidated a single 4k page or the
 	  whole IO/TLB for an address space. This has been extended now
 	  and is mostly useful for emulated AMD IOMMUs.
 
 	- Several fixes for the Shared Virtual Memory support in the
 	  Intel VT-d driver
 
 	- Mediatek drivers can now be built as modules
 
 	- Re-introduction of the forcedac boot option which got lost
 	  when converting the Intel VT-d driver to the common dma-iommu
 	  implementation.
 
 	- Extension of the IOMMU device registration interface and
 	  support iommu_ops to be const again when drivers are built as
 	  modules.

Pull iommu updates from Joerg Roedel:

 - Big cleanup of almost unsused parts of the IOMMU API by Christoph
   Hellwig. This mostly affects the Freescale PAMU driver.

 - New IOMMU driver for Unisoc SOCs

 - ARM SMMU Updates from Will:
     - Drop vestigial PREFETCH_ADDR support (SMMUv3)
     - Elide TLB sync logic for empty gather (SMMUv3)
     - Fix "Service Failure Mode" handling (SMMUv3)
     - New Qualcomm compatible string (SMMUv2)

 - Removal of the AMD IOMMU performance counter writeable check on AMD.
   It caused long boot delays on some machines and is only needed to
   work around an errata on some older (possibly pre-production) chips.
   If someone is still hit by this hardware issue anyway the performance
   counters will just return 0.
