- Enable the named address spaces based percpu accessors optimization
on all GCC versions that contain this feature, detected through
a build-time testcase. This effectively enables the feature on
GCC 6, GCC 7 and GCC 8 versions.
- Fix operand constraint modifier in __raw_cpu_write()
- Reorganize the per-CPU headers for better readability
- Misc cleanups and fixes

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.
