Bartosz Pawlowski 7b3a9c2bf3 PCI: Disable ATS for specific Intel IPU E2000 devices
commit a18615b1cfc04f00548c60eb9a77e0ce56e848fd upstream.

Due to a hardware issue in A and B steppings of Intel IPU E2000, it expects
wrong endianness in ATS invalidation message body. This problem can lead to
outdated translations being returned as valid and finally cause system
instability.

To prevent such issues, add quirk_intel_e2000_no_ats() to disable ATS for
vulnerable IPU E2000 devices.

README

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.
