Chris Wilson 41db645a33 drm/i915: Bump priority of clean up work
We require that we keep the list of outstanding work short so that we do
not "leak" memory while pageflipping under stress. However that system
stress may delay kernel workers virtually indefinitely, which incurs the
pageflips stall and eventually hit a timeout waiting for the cleanup.

Try to combat CPU starvation of our short-lived cleanup workers by
switching to a high priority workqueue.

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.
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.
