XCNTXT_MASK is 'all supported xfeatures' before introducing supervisor xstates. Rename it to XFEATURE_MASK_USER_SUPPORTED to make clear that these are user xstates. Replace XFEATURE_MASK_SUPERVISOR with the following: - XFEATURE_MASK_SUPERVISOR_SUPPORTED: Currently nothing. ENQCMD and Control-flow Enforcement Technology (CET) will be introduced in separate series. - XFEATURE_MASK_SUPERVISOR_UNSUPPORTED: Currently only Processor Trace. - XFEATURE_MASK_SUPERVISOR_ALL: the combination of above.

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.
