Ryan Roberts 912609e96c arm64/mm: export contpte symbols only to GPL users
Patch series "Address some contpte nits".

These 2 patches address some nits raised by Catalin late in the review cycle for
my contpte series [1].

This patch (of 2):

The contpte symbols must be exported since some of the public inline
ptep_* APIs are called from modules and these inlines now call the contpte
functions.  Originally they were exported as EXPORT_SYMBOL() for fear of
breaking out-of-tree modules.  But we subsequently concluded that
EXPORT_SYMBOL_GPL() should be safe since these functions are deeply core
mm routines, and any module operating at this level is not going to be
able to survive on EXPORT_SYMBOL alone.

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.
