For the upcoming kmapping i915 memcpy_move, export ttm_bo_tt_destroy(). A future change might be to move the new memcpy_move into ttm, replacing the old ioremapping one.
Well this is an upfront NAK for that approach.
I've worked quite hard to not export those functions any more since this is not something drivers should be allowed to mess with.
If you need this we should probably move the functionality into TTM instead.
