Subject: [git pull] IOMMU Updates for Linux v5.16
Hi Linus,
there is a merge conflict this time between the IOMMU tree and FPU
changes which came from the tip tree. My conflict resolution is
attached. With that in mind:
The following changes since commit 8bb7eca972ad531c9b149c0a51ab43a417385813:
Linux 5.15 (2021-10-31 13:53:10 -0700)

Merge branches 'apple/dart', 'arm/mediatek', 'arm/renesas', 'arm/smmu', 'arm/tegra', 'iommu/fixes', 'x86/amd', 'x86/vt-d' and 'core' into next (2021-10-31 22:26:53 +0100)
----------------------------------------------------------------
IOMMU Updates for Linux v5.16:
Including:
- Intel IOMMU Updates fro Lu Baolu:
- Dump DMAR translation structure when DMA fault occurs
- An optimization in the page table manipulation code
- Use second level for GPA->HPA translation
- Various cleanups
- Arm SMMU Updates from Will
- Minor optimisations to SMMUv3 command creation and submission
- Numerous new compatible string for Qualcomm SMMUv2 implementations
- Fixes for the SWIOTLB based implemenation of dma-iommu code for
untrusted devices
- Add support for r8a779a0 to the Renesas IOMMU driver and DT matching
code for r8a77980
- A couple of cleanups and fixes for the Apple DART IOMMU driver
- Make use of generic report_iommu_fault() interface in the AMD IOMMU
driver
- Various smaller fixes and cleanups
