Hi Dave,

After merging the drm tree, today's linux-next build (s390 allmodconfig)
failed like this:

drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:143:2: error: implicit declaration of function 'dma_to_phys' [-Werror=implicit-function-declaration]

Caused by commit

  69c4938249fb ("drm/nouveau/instmem/gk20a: use direct CPU access")

Discovered after the release.
