patch subject: [PATCH] drm/amdgpu: Implement mmap of imported dma-bufs
config: sparc-allyesconf
Well big NAK to this!
We have discussed this extensively on the mailing list and absolutely
don't want to allow that.
Only for some ARM drivers we failed to block that soon enough and will
keep the functionality around to not break userspace.
Regards,
Christian.

Use dmabuf mmap from exporting driver to do the mapping.
