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
