src/sys/external/bsd/drm2/dist/drm/nouveau: nouveau_bo.c nouveau_drm.h
Log Message:
provide a ttm-backed set of nouveau_uvm_ops{} in the ttm_bo_driver{}.
fixes NULL pointer derefs inside UVM due to lack of pager ops.
copy the DRM_FILE_PAGE_OFFSET vs !_LP64 workaround.
with these, X starts up on my GTX 440.
