[PATCH 3/8] lib/amdgpu: Add user mode queue support in ring context

[vitaly prosyak]

Hi Kamil,

I have sent the review to Sunil, but we were using the internal review process. I believe Sunil is aware of the build failure, and we discussed how to address it. Until the build failure is resolved and the header is updated or the new code is guarded, we will not proceed with the merge.

Thanks for your help!
