Should be fixed by 320d531373e7b0873f5de42f6173b986290f593f, thanks!
FWIW the command emit mechanism looks a bit too complicated it could profit
from some refactoring. For instance it is still based on the fake
drm_radeon_cmd_header_t structure, the scl vs. scl2 and vec vs. veclinear emits
are nothing but crude hacks around limitations in that structure, even though
since ums is gone there is absolutely no point in using that struct...
Section size calcs are also somewhat confusing, the sanity code (which was
really great back then) is totally unused etc.
Maybe another day...
