The shared memory buffer allocated by the optee driver is normal cached memory and can't be used with IOMEM APIs used in shmem_*. We currently support only IO memory for shared memory and supporting normal cached memory needs more changes and needs to be thought through properly. So for now, let us drop the support for this OPTEE shared buffer.

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.
