Chris Wilson f34a93bbb3 drm/i915: Check PIN_NONFAULT overlaps in evict_for_node
If the caller says that he doesn't want to evict any other faulting
vma, honour that flag. The logic was used in evict_something, but not
the more specific evict_for_node, now being used as a preliminary probe
since commit 606fec956c ("drm/i915: Prefer random replacement before
eviction search").

Fixes: 606fec956c ("drm/i915: Prefer random replacement before eviction search")
Fixes: 821188778b ("drm/i915: Choose not to evict faultable objects from the GGTT")

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
