Bug 53402

Hello nouveau developers and community,
I'm having issue's compiling latest HEAD (as of right now): 088fba1c7c7

CC drivers/gpu/drm/nouveau/nouveau_bo.o
drivers/gpu/drm/nouveau/nouveau_bo.c: In function 'nouveau_ttm_tt_create':
drivers/gpu/drm/nouveau/nouveau_bo.c:463:3: error: implicit declaration of function 'ttm_agp_tt_create'
drivers/gpu/drm/nouveau/nouveau_bo.c:463:3: attention: return makes pointer from integer without a cast

$ cat .config | grep NOUVEAU
CONFIG_DRM_NOUVEAU=y
CONFIG_NOUVEAU_DEBUG=5
CONFIG_NOUVEAU_DEBUG_DEFAULT=3
CONFIG_DRM_NOUVEAU_BACKLIGHT=y
I have posted my full .config @ http://pastebin.com/YuHnMnH4

Reverting commit d5ef81 (drm/nouveau: port remainder of drm code, and rip out compat layer) makes compilation go past this point. However, it crashes later because other bits and pieces rely on this specific commit.

Using Gentoo Hardened with GCC:
