----------------------------------------------------------------
IOMMU Updates for Linux v5.20/v6.0:

Including:

	- Most intrusive patch is small and changes the default
	  allocation policy for DMA addresses. Before the change the
	  allocator tried its best to find an address in the first 4GB.
	  But that lead to performance problems when that space gets
	  exhaused, and since most devices are capable of 64-bit DMA
	  these days, we changed it to search in the full DMA-mask
	  range from the beginning.  This change has the potential to
	  uncover bugs elsewhere, in the kernel or the hardware. There
	  is a Kconfig option and a command line option to restore the
	  old behavior, but none of them is enabled by default.

	- Add Robin Murphy as reviewer of IOMMU code and maintainer for
	  the dma-iommu and iova code

	- Chaning IOVA magazine size from 1032 to 1024 bytes to save
	  memory

	- Some core code cleanups and dead-code removal

	- Support for ACPI IORT RMR node

	- Support for multiple PCI domains in the AMD-Vi driver

	- ARM SMMU changes from Will Deacon:

	  - Add even more Qualcomm device-tree compatible strings

	  - Support dumping of IMP DEF Qualcomm registers on TLB sync
	    timeout

	  - Fix reference count leak on device tree node in Qualcomm
	    driver

	- Intel VT-d driver updates from Lu Baolu:

	  - Make intel-iommu.h private

	  - Optimize the use of two locks

	  - Extend the driver to support large-scale platforms

	  - Cleanup some dead code

	- MediaTek IOMMU refactoring and support for TTBR up to 35bit

	- Basic support for Exynos SysMMU v7

	- VirtIO IOMMU driver gets a map/unmap_pages() implementation

	- Other smaller cleanups and fixes
