Will Deacon 113eb4ce4f Merge branch 'for-next/iommu/vt-d' into for-next/iommu/core
Intel VT-D updates for 5.11. The main thing here is converting the code
over to the iommu-dma API, which required some improvements to the core
code to preserve existing functionality.

* for-next/iommu/vt-d:
  iommu/vt-d: Avoid GFP_ATOMIC where it is not needed
  iommu/vt-d: Remove set but not used variable
  iommu/vt-d: Cleanup after converting to dma-iommu ops
  iommu/vt-d: Convert intel iommu driver to the iommu ops
  iommu/vt-d: Update domain geometry in iommu_ops.at(de)tach_dev
  iommu: Add quirk for Intel graphic devices in map_sg
  iommu: Allow the dma-iommu api to use bounce buffers
  iommu: Add iommu_dma_free_cpu_cached_iovas()
  iommu: Handle freelists when using deferred flushing in iommu drivers
  iommu/vt-d: include conditionally on CONFIG_INTEL_IOMMU_SVM

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
