xe_bo_move() might be called in the TTM swapout path from validation by another TTM device. If so, we are not likely to have a RPM reference. So iff xe_pm_runtime_get() is safe to call from reclaim, use it instead of xe_pm_runtime_get_noresume(). Strictly this is currently needed only if handle_system_ccs is true, but use xe_pm_runtime_get() if possible anyway to increase test coverage. At the same time warn if handle_system_ccs is true and we can't call xe_pm_runtime_get() from reclaim context. This will likely trip if someone tries to enable SRIOV on LNL, without fixing Xe SRIOV runtime resume / suspend.

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.
