Herbert Xu e4da95e124 crypto: marvell/cesa - Do not chain submitted requests 
commit 0413bcf0fc upstream.

This driver tries to chain requests together before submitting them
to hardware in order to reduce completion interrupts.

However, it even extends chains that have already been submitted
to hardware.  This is dangerous because there is no way of knowing
whether the hardware has already read the DMA memory in question
or not.

Fix this by splitting the chain list into two.  One for submitted
requests and one for requests that have not yet been submitted.
Only extend the latter.

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.
