I looked at nouveau before writing this code, thing is, in the end
there is little common code especialy when you take different path on
how you handle things (persistent or dynamic page table for instance).
Thought couple things can still be share. Note that the whole radeon
code is designed with the possibility of having several address space
per process, thought there is no use for such things today we believe
things like opencl+opengl can benefit of each having their own address
space.
