Nirmoy Das 38c4c8722b drm/xe/ufence: Flush xe ordered_wq in case of ufence timeout 
Flush xe ordered_wq in case of ufence timeout which is observed
on LNL and that points to recent scheduling issue with E-cores.

This is similar to the recent fix:
commit e515272338 ("drm/xe/guc/ct: Flush g2h worker in case of g2h
response timeout") and should be removed once there is a E-core
scheduling fix for LNL.

v2: Add platform check(Himal)
    s/__flush_workqueue/flush_workqueue(Jani)
v3: Remove gfx platform check as the issue related to cpu
    platform(John)
v4: Use the Common macro(John) and print when the flush resolves
    timeout(Matt B)

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.
