[git pull] IOMMU Fixes for Linux v7.1-rc3

[Joerg Roedel]

Hi Linus,

This is probably the largest fixes pull-request ever sent for IOMMU. I
partially blame it to AI code review which found some issues but there is also
some rework in here to fix issues in the iommu parts of PCI device reset. I
hope that is okay, if not I can send a smaller PR, just let me know.

With that said:

The following changes since commit 5d6919055dec134de3c40167a490f33c74c12581:

----------------------------------------------------------------
IOMMU Fixes for Linux v7.1-rc3:

Including:

	- AMD-Vi:
	  - Add bounds checks to debugfs and table lookups

	- Intel VT-d:
	  - Apply an existing quirk for Q35 graphic device.
	  - Skip dev_pasid teardown for the blocked domain to avoid out-of-bounds
	    access.
	  - Return early if dev_pasid is missing to prevent NULL dereference or
	    UAF.

	- Core:
	  - Fix bugs and corner cases in the pci_dev_reset_iommu_prepare/done()
	    code. This are some bigger changes including some re-work,
	    hopefully okay for -rc.
	  - Fix various issues found by AI in iommupt code.

	- MAINTAINERS email address update for RISCV IOMMU.
