Geetha sowjanya 4070cf004d octeontx2-pf: cn10k: Ensure valid pointers are freed to aura 
[ Upstream commit c5d731c54a ]

While freeing SQB pointers to aura, driver first memcpy to
target address and then triggers lmtst operation to free pointer
to the aura. We need to ensure(by adding dmb barrier)that memcpy
is finished before pointers are freed to the aura. This patch also
adds the missing sq context structure entry in debugfs.

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.
