71d3f6ef7f drm/virtio: fix framebuffer sparse warning 
virtio uses normal ram as backing storage for the framebuffer, so we
should assign the address to new screen_buffer (added by commit
17a7b0b4d9749f80d365d7baff5dec2f54b0e992) instead of screen_base.

e59a03f581 drm/virtio: use DRM_FB_HELPER_DEFAULT_OPS for fb_ops 
This patch removes a TODO comment in the code. I do not know whether it
is still relevant.

cb1197173f drm: Remove unused fbdev_list members 
I noticed that intel_fbdev->our_mode is unused. Introduced by
79e539453b34 ("DRM: i915: add mode setting support").

Then I noticed that intel_fbdev->fbdev_list is unused as well.
Introduced by 386516744ba4 ("drm/fb: fix fbdev object model +
cleanup properly.") in i915, nouveau and radeon.

Subsequently cargo culted to amdgpu, ast, cirrus, qxl, udl,
virtio and mgag200.

Already removed from the latter with cc59487a05b1 ("drm/mgag200:
'fbdev_list' in 'struct mga_fbdev' is not used").

Remove it from the others.

0843010bbd drm/virtio: Use new drm_fb_helper functions 
Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.

v3:
- Don't touch remove_conflicting_framebuffers

v2:
- add missing header for virtgpu_fb.c

2b7edcad69 drm/virtio: checking for NULL instead of IS_ERR 
virtio_gpu_alloc_object() returns an error pointer, it never returns
NULL.

dc5698e80c Add virtio gpu driver. 
This patch adds a kms driver for the virtio gpu.  The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.

Qemu patches for the host side are under review currently.

The pci version of the device comes in two variants: with and without
vga compatibility.  The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device.  The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.

Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.
