Add code to "complete" a descriptor when the descriptor or its completion address hit a fault error when SVA mode is being used. This error can be triggered due to bad programming by the user. A lock is introduced in order to protect the descriptor completion lists since the fault handler will run from the system work queue after being scheduled in the interrupt handler.

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.
