Thomas Zimmermann 6293eb2891 Revert "drm/vgem: Implement mmap as GEM object function"
Commit 375cca1cfe ("drm/vgem: Implement mmap as GEM object function")
broke several IGT tests in vgem_basic. [1] Attempts to fix the issue
have not worked out so far. [2][3] Revert the change for now.

Note that there is a patch that converts vgem to shmem helpers. [4]
Merging this change would be preferable to modifying vgem's mmap code.

v2:
	* fix spelling error in commit message (Daniel)

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.
