Pull IOMMU fixes from Joerg Roedel: - Revert an Intel VT-d patch that caused problems for some users. - Removal of a feature in the Intel VT-d driver that was never supported in hardware. This qualifies as a fix because the code for this feature sets reserved bits in the invalidation queue descriptor, causing failed invalidations on real hardware. - Two fixes for AMD IOMMU driver to fix a race condition and to add a missing IOTLB flush when kernel is booted in kdump mode. * tag 'iommu-fixes-v5.3-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Fix race in increase_address_space() iommu/amd: Flush old domains in kdump kernel iommu/vt-d: Remove global page flush support Revert "iommu/vt-d: Avoid duplicated pci dma alias consideration"
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.
