Linus Torvalds 6e5772c8d9 Add an interface called cc_platform_has() which is supposed to be used
by confidential computing solutions to query different aspects of the
 system. The intent behind it is to unify testing of such aspects instead
 of having each confidential computing solution add its own set of tests
 to code paths in the kernel, leading to an unwieldy mess.

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.
