[ Upstream commit094d00f8ca] CMOs issued from EL2 cannot directly use the kernel helpers, as EL2 doesn't have a mapping of the guest pages. Oops. Instead, use the mm_ops indirection to use helpers that will perform a mapping at EL2 and allow the CMO to be effective.

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.
