The feature was never merged and there has been no progress in the
last year. The subtests are currently skipping on all platforms by
checking a field in the get_aperture ioctl structure that doesn't
exist in the kernel version of the struct.
The interface for this is upstream, fix the test to exercise the kernel
code (hint dmabuf).

I'm not very familiar with the dmabuf interface, but looking at it I
couldn't find any way of allocating and/or accessing an object in stolen
memory from userspace. A grep for "create_stolen" also didn't show
anything. Can you point me in the right direction?
Thanks,
Daniele
