Thomas Hellström 1364a9ead4 drm/xe/pm: Hold the validation lock around evicting user-space bos for suspend
During pm notifier eviction we may still race with validations.
Ensure those are blocked out during eviction to ensure we have
access to as much system memory as possible.

During the suspend operation itself, we run single-threaded so that
shouldn't be a problem.

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.
