[PATCH 0/4] drm/nouveau: Remove struct nouveau_framebuffer

[Thomas Zimmermann]

All fields in struct nouveau_framebuffer appear to be obsolete. The
data structure can be replaced by struct drm_framebuffer entirely.

Patch 1 removes several unused fields from struct nouveau_framebuffer.

Patch 2 moves the field vma to struct nouveau_fbdev. The information
in vma is only relevant for fbdev emulation, and as such he field is
only used there.

Patch 3 removes nvbo from struct nouveau_framebuffer. The nouveau
buffer object is based on gem, and as such should be stored in obj[0]
of struct drm_framebuffer. This also enables the use of several generic
GEM framebuffer functions.

Finally patch 4 removes struct nouveau_framebuffer. At this point it's
merely a wrapper around struct drm_framebuffer.

The patchset has been smoke-tested on NV34 HW by running fbcon and X11.

Future directions: There are still functions for creating frameuffers.
With further refinements of nouveau's fbcon code, GEM framebuffer helpers
could be used here.
