Chris Wilson 280d14a69d drm/i915/gem: Tighten checks and acquiring the mmap object 
Make sure we hold the rcu lock as we acquire the rcu protected reference
of the object when looking it up from the associated mmap vma.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1083
Fixes: cc662126b4 ("drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSET")

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 Restructured Text 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.
