commit 0eb8e74f7202a4a98bbc0c1adeed3986cf50b66a upstream. We're missing a workaround in the fbc code for all glk+ platforms which can cause corruption around the top of the screen. So enabling fbc by default is a bad idea. I'm not keen to backport the w/a so let's start by disabling fbc by default on all glk+. We'll lift the restriction once the w/a is in place.

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.
