Yes pretty much all is use, the unuse case is SOFT_DIRTY and CLEAR
vs UNMAP. Both of which i intend to use. The RDMA folks already ack
the patches IIRC, so did radeon and amdgpu. I believe the i915 folks
were ok with it too. I do not want to merge things through Andrew
for all of this we discussed that in the past, merge mm bits through
Andrew in one release and bits that use things in the next release.
