- Replace magic numbers in GDT descriptor definitions & handling:
- Introduce symbolic names via macros for descriptor types/fields/flags,
and then use these symbolic names.
- Clean up definitions a bit, such as GDT_ENTRY_INIT()
- Fix/clean up details that became visibly inconsistent after the
symbol-based code was introduced:
- Unify accessed flag handling
- Set the D/B size flag consistently & according to the HW specification

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.
