Add support for new processors which have multiple PCI root complexes per data fabric/system management network interface. If there are (N) multiple PCI roots per DF/SMN interface, then the PCI roots are redundant (as far as SMN/DF access goes). For each DF/SMN interface: map to the first available PCI root and skip the next N-1 PCI roots so the following DF/SMN interface get mapped to a correct PCI root. Ex: DF/SMN 0 -> 60 40 20 00 DF/SMN 1 -> e0 c0 a0 80 Signed-off-by: Brian Woods <brian.woods@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de> CC: Bjorn Helgaas <bhelgaas@google.com> CC: Clemens Ladisch <clemens@ladisch.de> CC: Guenter Roeck <linux@roeck-us.net> CC: "H.

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.
