Linus Torvalds 36a14638f7 Two fixes: 
- Fix build failure on Ubuntu with new GCC packages that turn on -fcf-protection
 
  - Fix SME memory encryption PTE encoding bug - AFAICT the code worked on
    4K page sizes (level 1) but had the wrong shift at higher page level orders
    (level 2 and higher).

README 

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.
