[PATCH 09/17] drm/radeon: use common fence implementation for fences
...t it doesn't apply to radeon and nouveau,
but for other drivers that could be necessary, like vmwgfx.
Ironically that is also a part of the ttm fence, except it was called flush there.
I would also like to note that ttm_bo_wait currently is also a function that currently uses is_signaled from atomic_context...
For the more complicated locking worries: Lockdep is your friend, use PROVE_LOCKING and find bugs before they trigger. ;-)

Then call it flush again and make it optional like in TTM.

I know, but TTM is only called from inside a single driver, no inter
driver needs here. We currently even call the internal fence
implementation from interrupt context as well and at more than one
occasion assume that TTM only uses radeon fences.
