Subject[PATCH 4.4 51/56] drm/vmwgfx: Fix Ubuntu 17.10 Wayland black screen issue
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sinclair Yeh <syeh@vmware.com>

commit cef75036c40408ba3bc308bcb00a3d440da713fc upstream.

This is an extension of Commit 7c20d213dd3c ("drm/vmwgfx: Work
around mode set failure in 2D VMs")

With Wayland desktop and atomic mode set, during the mode setting
process there is a moment when two framebuffer sized surfaces
are being pinned. This was not an issue with Xorg.

Since this only happens during a mode change, there should be no
performance impact by increasing allowable mem_size.
