This includes a major refactoring of the fbcon packed pixel drawing routines,
contributed by Zsolt Kajtar. The original version duplicated more or less the
same algorithms for both system and i/o memory. The new implementation is more
robust, both implementations are now feature complete (e.g. pixel order
reversing now supported by both), behaves the same way as it uses the identical
code for both variants and adds support for foreign endian framebuffers.
The other fixes and cleanups are:
- dummycon: only build module if there are users and fix rows/cols (Arnd Bergmann)
- mdacon: rework dependency list (Arnd Bergmann)
- lcdcfb, fsl-diu-fb, fbcon: Fix registering and removing of sysfs (Shixiong Ou)
- sm501fb: Add some geometry checks (Danila Chernetsov)
- omapfb: Remove unused code, add value checks (Leonid Arapov)
- au1100fb: Clean up variable assignment (Markus Elfring)
- pxafb: use devm_kmemdup*() (Raag Jadav)

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 reStructuredText 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.
