Kim Phillips 774c63f536 iommu/amd: Fix ill-formed ivrs_ioapic, ivrs_hpet and ivrs_acpihid options
[ Upstream commit 1198d2316dc4265a97d0e8445a22c7a6d17580a4 ]

Currently, these options cause the following libkmod error:

libkmod: ERROR ../libkmod/libkmod-config.c:489 kcmdline_parse_result: \
	Ignoring bad option on kernel command line while parsing module \
	name: 'ivrs_xxxx[XX:XX'

Fix by introducing a new parameter format for these options and
throw a warning for the deprecated format.

Users are still allowed to omit the PCI Segment if zero.

Adding a Link: to the reason why we're modding the syntax parsing
in the driver and not in libkmod.

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.
