Including: - AMD IOMMU Fix to make sure features are detected before they are queried. - Intel IOMMU address alignment check fix for an IOLTB flushing command. - Performance fix for Intel IOMMU to make sure the code does not do full IOTLB flushes all the time. Those flushes are very expensive on emulated IOMMUs. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAmAUOaQACgkQK/BELZcB GuO2hQ/9HOWNK4R06JufpOy+G29M4nY74RkfB2DuFjamouKkgSEODyv9bzz6Rhn6 WvTPzIxhaFuaw5MCiOp1a80CnzP9rPLn8zMAG9jSh4dHMnIvCZsXrJJkIT1NIBOH Sryz1tqu3MNWvOauoQnopRSbmhlEMTfgOY62Tn4bcz92Y49LH5/gb0Wcz/YZbFZd q3f3UKI2xOTB2nGckxGEOMtpWSkaeNZs4GhPl9HwFXUwkNgPleVJZcnx/KL6fPRk WTmPOgf7EVoVr/2aAtLvEWwZIJ6OE0D1AgYgPn6y18UsBYQiAz1/5k+M2r1lJo5L UKnjSsRuybAO6aQwRdl7kQXk9bTzU0D7tVqMvWLsiJP02U/+0LiRH1WIY+eWnkRt syHBWTYQFqLryHmXyy7rNEEslqgidP+SBSH6NDdzKJR5OwjzAqNgrnMxIlciL/n0 1hlwR3B5OjliHilMZo8/Bc9XzAMlK7nl5EpMcCvhYocX5pJV1FQrOhrIgRASWVZ4 Ce+F4RxgbpyYihDNg3PpE2DMh/5OjxXCIsTGh5BA4AQgINrRe6ETwh6Vw3NBJI5k T7L/MVqo59nBPPZ5RmVdyl6XjTTHFMt8C9zpnNg4LbOuNUP0Udm0vLaiJKldzg5B oth+P7ftg9H9KJtOQtkfSP8A/WCaHRqHJOuMwZ53eb7EL+JEq0E= =djR4 -----END PGP SIGNATURE----- Merge tag 'iommu-fixes-v5.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu fixes from Joerg Roedel: - AMD IOMMU fix to make sure features are detected before they are queried. - Intel IOMMU address alignment check fix for an IOLTB flushing command. - Performance fix for Intel IOMMU to make sure the code does not do full IOTLB flushes all the time.

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.
