Including: - Fix a bug in the AMD IOMMU driver not handling exclusion ranges correctly. In fact the driver did not reserve these ranges for IOVA allocations, so that dma-handles could be allocated in an exclusion range, leading to data corruption. Exclusion ranges have not been used by any firmware up to now, so this issue remained undiscovered for quite some time. - Fix wrong warning messages that the IOMMU core code prints when it tries to allocate the default domain for an iommu group and the driver does not support any of the default domain types (like Intel VT-d). -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAlyeRXwACgkQK/BELZcB GuMQZBAAx3x0217aR5Gu9IrpW4ippM96czOLYJZvacDUujHyoTYTrNe7DlG90jYC Cx0/zxycxmd7nknVWm8uRIqPy1iPnsD+Sb5TsCYewIV5RkcnXLUCUGFyq7aQpgqw xw5nto1MwO9blLJLleFKT1Cs8fuojYvBg7zszgjtkQKtNJK7Vm6kO86VegDujtPj gDSWjDUQ/S3o07We17qYuFwJ4fTC5ItP+GwW72dGIeGJFNRG6SF4YQs44G+yUpZD Vsbyjs0F983IOiRblYONlOqiROxm1vptJgr4ZfOxwZ7+htx+g/YW9UbP52HKPlCP WEpsNl+AK6GnW0wCxEzeSQ6pO6EXGiBdA6darx73hjeviImWYs5MirRUF4b/+IMR YLXVT4zb3DHqXGf7qCu4yAFnrtzU7uEw0+S/J/0R5A1ILYhDWVRiPP6Ph/8n4fLp XUYieFNX/2uNJOZratvrKY/H+ccA2HZBhXbftXkfCbxnZfZTEX7ay0FrOvNbMz/t 70PscX1+SF28Hk4ejqjYT8HZf7YU+6QY9PZZi+PjwtqCiWww/tde7Ej/4h8v98vY 1qhxBS2ZeAraTYo1dL4vaMSFuyaJfTuF4a04nl65CoKi9KLs1/6Rwq7/383XJYCT OH/AqwY69LgVczjQzQ/HPGbuMieNRFtR+N+KXXccC31StYdtz3w= =HY4V -----END PGP SIGNATURE----- Merge tag 'iommu-fixes-v5.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU fixes from Joerg Roedel: - Fix a bug in the AMD IOMMU driver not handling exclusion ranges correctly.

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.
