iommu/vt-d: Handle 36bit addressing for x86-32 (2020-09-04 12:14:28 +0200)

----------------------------------------------------------------
IOMMU Fixes for Linux v5.9-rc3

Including:

- Three Intel VT-d fixes to fix address handling on 32bit, fix a
NULL pointer dereference bug and serialize a hardware register
access as required by the VT-d spec.

- Two patches for AMD IOMMU to force AMD GPUs into translation mode
when memory encryption is active and disallow using IOMMUv2
functionality. This makes the AMDGPU driver working when
memory encryption is active.

- Two more fixes for AMD IOMMU to fix updating the Interrupt
Remapping Table Entries.

- MAINTAINERS file update for the Qualcom IOMMU driver.
