Nirmoy Das 528cef1b41 drm/xe: Use non-interruptible wait when moving BO to system
Ensure a non-interruptible wait is used when moving a bo to
XE_PL_SYSTEM. This prevents dma_mappings from being removed prematurely
while a GPU job is still in progress, even if the CPU receives a
signal during the operation.

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.
