This was originally just a patch to add an AMD IOMMU
documentation page, but grew into some cleanup of the
Intel IOMMU documentation page.
v2: AMD documentation rework
Add Intel Updates
v3: Further documentation reworks
Alex Deucher (2):
Documentation: x86: Add documentation for AMD IOMMU
Add preliminary documentation for AMD IOMMU.
Signed-off-by: Alex Deucher

V2: Incorporate feedback from Robin to clarify IOMMU vs DMA engine (e.g.,
a device) and document proper DMA API. Also correct the fact that
the AMD IOMMU is not limited to managing PCI devices.
v3: Fix
Based on feedback from Robin on the initial AMD IOMMU
documentation, fix up the Intel documentation to
clarify IOMMU vs device and modern DMA API.
Signed-off-by: Alex Deucher
---
V2: Fix spelling error in commit message
Rework ACPI section as suggested by Dave Hansen
Documentation/x86
Add preliminary documentation for AMD IOMMU and combine
with the existing Intel IOMMU documentation and clean
up and modernize some of the existing documentation to
align with the current state of the kernel.
