Johnny-CC Chang cbda385589 PCI: Mark Nvidia GB10 to avoid bus reset 
[ Upstream commit c81a2ce6b6 ]

After asserting Secondary Bus Reset to downstream devices via a GB10 Root
Port, the link may not retrain correctly, e.g., the link may retrain with a
lower lane count or config accesses to downstream devices may fail.

Prevent use of Secondary Bus Reset for devices below GB10.

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 reStructuredText 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.
