Also can't see why this was like this. This option predates KFD's support of userptrs, which in turn predates HMM. Radeon has the same kind of option, though it doesn't affect HMM in that case. Alex, Christian, can you think of a good reason to maintain userptr support as an option in amdgpu? I suspect it was originally meant as a way to allow kern...

Hi all, this series improves the use_mm / unuse_mm interface by better documenting the assumptions, and my taking the set_fs manipulations spread over the callers into the core API.
