Matthew Brost 4ac9048d05 drm/xe: Wait on in-syncs when swicthing to dma-fence mode
If a dma-fence submission has in-fences and pagefault queues are running
work, there is little incentive to kick the pagefault queues off the
hardware until the dma-fence submission is ready to run. Therefore, wait
on the in-fences of the dma-fence submission before removing the
pagefault queues from the hardware.

v2:
 - Fix kernel doc (CI)
 - Don't wait under lock (Thomas)
 - Make wait interruptable

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 reStructuredText 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.
