The big theme for this release has been performance, we've had a series
of unrelated overhauls of a few drivers all with a big peformance
component. Otherwise it's been relatively quiet, highlights include:
- A big overhaul of the spi-fsl-dspi driver improving the code quality,
performance and stability from Vladimir Oltean.
- A big performance enhancement for the bc2835 (Raspberry Pi) driver
for unidirectional transfers from Lukas Wunner.
- Improved performance on small transfers for the uniphier driver from
Keiji Hayashibara.
- Lots of coccinelle generated cleanups from Yue Haibing.
- New device support for Freescale ls2080a and Nuvoton NPCM FIU.

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.
