A mirror of the official Linux kernel repository just in case

Pre 5.11 kernels don't support 'contextid1' and 'contextid2' so
validation would be skipped. By adding an additional check for
'contextid', old kernels will still have validation done even though
contextid would either be contextid1 or contextid2.
Additionally now that it's possible to override options, an existing bug
in the validation is revealed. 'val' is overwritten by the contextid1
validation, and re-used for contextid2 validation causing it to always
fail. '!val || val != 0x4' is the same as 'val != 0x4' because 0 is also
!= 4, so that expression can be simplified and the temp variable not
overwritten.

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.
