Including: - ATS support for ARM-SMMU-v3. - AUX domain support in the IOMMU-API and the Intel VT-d driver. This adds support for multiple DMA address spaces per (PCI-)device. The use-case is to multiplex devices between host and KVM guests in a more flexible way than supported by SR-IOV. - The Rest are smaller cleanups and fixes, two of which needed to be reverted after testing in linux-next. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAlzZWPkACgkQK/BELZcB GuPdRRAAj/RcgVn7fqmNDM02xe6C5PuwBGYkXnC+atDrTQWbFsM0JE3YTWEHJ+66 7RMoYaksRaSBsn3QuX3b6+g6E+exhGoQ0BfkmuF8StUXAsaxvzGxvuk+cP0o4/mK pZkj3BddS4ycRqQPsVEbgJGRzL39dxWHe7p3/FfwgV+HzVonURFozU0HixLAoBhr uS0LpBiG8uGCMvO6yhTmPmfrbsSAcMivb7LlmsaykXPhjBk7kSqNgHNNx5O+HC8m XJdFatkxolkrN6A2FoHdP05sAXCv+uHbAGGGitYziRaXG7GBzm7Vc2LspJIml+y2 898+MiTH1M3P0WPyDa3cfcnRc2BBuJg56emad4CcfduM9sVXI0Ol6slNAYljnSYD 5A0CUxbrLxGUZaf6DAUJ9w5L+LhgEkXzKWEE9Nif46K4I1CFSt/d8nwB6Q5Oc/ie GZwTICRkMwTeqOM/CTyvwJCCwZm47AVv3qwaI0z5oDplH/bbRmNEi5WFJsgcgOnd GS5kmzjFBsljjDVWswgugdm7sdMSl7y88uQK9zUiG8fXgRiVUW/rENfZ1SMmVl1p zBQDndZmtrHm5ybe/NAZ8vaJhk4i1F3rWT0hwRZZKGDIrd/C3egnNyYkc4XeTPGe 3il+dJleIIwOX5Fpa44XTV1rDuVOXpF5LS5NRLjhhd+XqbaXZFI= =HLtu -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull IOMMU updates from Joerg Roedel: - ATS support for ARM-SMMU-v3. - AUX domain support in the IOMMU-API and the Intel VT-d driver.

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.
