Subject: drm/ttm: remove nonsense AGP handling
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4127a6204970b3d7cb140117472eb3dd99bd1a0d;p=linux.git

drm/ttm: remove nonsense AGP handling

map_page_into_agp() and unmap_page_from_agp() are only defined on x86.

On all other platforms they are defined as noops. So this code doesn't has any effect at all.
