[ Upstream commit 55dc2f8f263448f1e6c7ef135d08e640d5a4826e ] Since screen_info.lfb_base is a __u32 type, an above-4G address need an ext_lfb_base to present its higher 32bits. In init_screen_info() we can use __screen_info_lfb_base() to handle this case for reserving screen info memory.

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.
