DMA_SHARED_BUFFER can not be enabled by the user (it represents a
library
set in the kernel). The kconfig convention is to use select for such
symbols so they are turned on implicitly when the user enables a kconfig
that needs them.
Otherwise the XEN_GNTDEV_DMABUF kconfig is overly difficult to enable.

Thanks Oleksandr and Juergen, can you also give me some advice on how
to progress the more complex patch:
https://patchwork.kernel.org/patch/11191369/
Is this gntdev stuff still in-use? I struggled a bit to understand
what it is doing, but I think I made a reasonable guess?
I think Jurgen and Boris could help here
Jason
