Hi, hohannes
You may need to build mesa with --enable-ttm-api, and update drm kernel
modules as well whose source is under drm/linux-core,
it depends on another kernel symbol to be exported, so you need to apply
following to your kernel
diff --git a/mm/shmem.c b/mm/shmem.c
index e2a6ae1..069ff39 100644
