[ Upstream commit c8de8ed2dc ]
The ACS quirks differ in needless ways, which makes them look more
different than they really are.
Reorder the ACS flags in order of definitions in the spec:
PCI_ACS_SV Source Validation
PCI_ACS_TB Translation Blocking
PCI_ACS_RR P2P Request Redirect
PCI_ACS_CR P2P Completion Redirect
PCI_ACS_UF Upstream Forwarding
PCI_ACS_EC P2P Egress Control
PCI_ACS_DT Direct Translated P2P
(PCIe r5.0, sec 7.7.8.2) and use similar code structure in all. No
functional change intended.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
