Linus Torvalds 6b04014f3f IOMMU Updates for Linux v5.3
Including:
 
 	- Patches to make the dma-iommu code more generic so that it can
 	  be used outside of the ARM context with other IOMMU drivers.
 	  Goal is to make use of it on x86 too.
 
 	- Generic IOMMU domain support for the Intel VT-d driver. This
 	  driver now makes more use of common IOMMU code to allocate
 	  default domains for the devices it handles.
 
 	- An IOMMU fault reporting API to userspace. With that the IOMMU
 	  fault handling can be done in user-space, for example to
 	  forward the faults to a VM.
 
 	- Better handling for reserved regions requested by the
 	  firmware. These can be 'relaxed' now, meaning that those don't
 	  prevent a device being attached to a VM.
 
 	- Suspend/Resume support for the Renesas IOMMU driver.
 
 	- Added support for dumping SVA related fields of the DMAR table
 	  in the Intel VT-d driver via debugfs.
 
 	- A pile of smaller fixes and cleanups.
