Linus Torvalds 4b205766d8 IOMMU Fixes for Linux v5.6-rc2
Including:
 
 	- Compile warning fix for the Intel IOMMU driver
 
 	- Fix kdump boot with Intel IOMMU enabled and in passthrough
 	  mode
 
 	- Disable AMD IOMMU on a Laptop/Embedded platform because the
 	  delay in introduces in DMA transactions causes screen
 	  flickering there with 4k monitors
 
 	- Make domain_free function in QCOM IOMMU driver robust and not
 	  leak memory/dereference NULL pointers
 
 	- Fix ARM-SMMU module parameter prefix names
