Zhenyu Wang 34869776c7 drm/i915: check ppgtt validity when init reg state
Check if ppgtt is valid for context when init reg state. For gvt
context which has no i915 allocated ppgtt, failed to check that
would cause kernel null ptr reference error.

v2: remove !48bit ppgtt case as we'll always update before submit (Chris)

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.
