[ Upstream commit 3db93756b501e5f0a3951c79cfa9ed43c26d3455 ]

mm-&gt;color_adjust() compares the hole with its neighbouring nodes. They
only abutt before we restrict the hole, so we have to apply color_adjust
before we apply the range restriction.

[ Upstream commit 7357f89954b6d005df6ab8929759e78d7d9a80f9 ]

I reported the include issue for tracepoints a while ago, but nothing
seems to have happened. Now it bit us, since the drm_mm_print
conversion was broken for armada. Fix it, so I can re-enable armada
in the drm-misc build configs.

v2: Rebase just the compile fix on top of Chris' build fix.

<title>drm/vmwgfx: Fix Ubuntu 17.10 Wayland black screen issue</title>

<content type='text'>
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.

commit 65e93108891e571f177c202add9288eda9ac4100 upstream.

We recently added an integer overflow check but it needs an additional
tweak to work properly on 32 bit systems.

The problem is that we're doing the right hand side of the assignment as
type unsigned long so the max it will have an integer overflow instead
of being larger than SIZE_MAX.  That means the "sz &gt; SIZE_MAX" condition
is never true even on 32 bit systems.  We need to first cast it to u64
and then do the math.

commit 77913bbcb43ac9a07a6fe849c2fd3bf85fc8bdd8 upstream.

Even though we've zeroed the PDE, the GPU may have cached the PD, so we
need to flush when deleting them.

Noticed while working on replacement MMU code, but a backport might be a
good idea, so let's fix it in the current code too.
