well, to be fair, if you are using a gpu on the client side and pixman
backend on the server side, you probably deserve the results.

Not to say that we shouldn't come up with a better way for sw access
to dmabuf, but just saying there are folks out there who would find
Benjamin's patch useful in it's current state (for example, platforms
where you have open src bits for video decoder but not for gpu).

So I wouldn't block this patch strictly because we don't have a better
mmap story yet.
