Sibi Sankar 2b5e61da68 remoteproc: qcom_q6v5_mss: map/unmap mpss segments before/after use 
[ Upstream commit be050a3429f46ecf13eb2b80f299479f8bb823fb ]

The application processor accessing the mpss region when the Q6 modem is
running will lead to an XPU violation. Fix this by un-mapping the mpss
segments post copy during mpss authentication and coredumps.

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.
