Maarten Lankhorst c6bcc0c2fd drm/i915: Reject UNSYNCHRONIZED for userptr, v2.
We should not allow this any more, as it will break with the new userptr
implementation, it could still be made to work, but there's no point in
doing so.

Inspection of the beignet opencl driver shows that it's only used
when normal userptr is not available, which means for new kernels
you will need CONFIG_I915_USERPTR.

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.
