Erdem Aktas 7c662f69fa percpu: Separate decrypted varaibles anytime encryption can be enabled 
commit 264b0d2bee upstream.

CONFIG_VIRTUALIZATION may not be enabled for memory encrypted guests.  If
disabled, decrypted per-CPU variables may end up sharing the same page
with variables that should be left encrypted.

Always separate per-CPU variables that should be decrypted into their own
page anytime memory encryption can be enabled in the guest rather than
rely on any other config option that may not be enabled.

Fixes: ac26963a11 ("percpu: Introduce DEFINE_PER_CPU_DECRYPTED")

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.
