Subject: DRM framebuffer removal broken since 13803132

Hi!

The commit

Subject: [PATCH] drm/core: Preserve the framebuffer after removing it.

badly breaks vmwgfx multimon since the crtcs are no longer turned off at
framebuffer removal,
which is part of the user-space contract.

Also isn't this a security issue, since at, for example, Xorg crash, the
crtcs can be left scanning out from memory
DRM no longer owns?

/Thomas
