Arun Kumar Neelakantam df9c43b0a8 rpmsg: glink: smem: Support rx peak for size less than 4 bytes
commit 928002a5e9dab2ddc1a0fe3e00739e89be30dc6b upstream.

The current rx peak function fails to read the data if size is
less than 4bytes.

Use memcpy_fromio to support data reads of size less than 4 bytes.

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
