Saravana Kannan 4a48b66b3f of: property: Disable fw_devlink DT support for X86 
Andre reported fw_devlink=on breaking OLPC XO-1.5 [1].

OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate
devices. The root cause seems to be ISA devices not setting their fwnode
field. But trying to figure out how to fix that doesn't seem worth the
trouble because the OLPC devicetree is very sparse/limited and fw_devlink
only adds the links causing this issue. Considering that there aren't many
users of OF in an X86 system, simply fw_devlink DT support for X86.

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.
