Linus Torvalds c76431e3b5 - Use the proper accessors when reading CR3 as part of the page level
transitions (5-level to 4-level, the use case being kexec) so that
   only the physical address in CR3 is picked up and not flags which are
   above the physical mask shift
 
 - Clean up and unify __phys_addr_symbol() definitions

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 reStructuredText 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.
