ttm_resource can be subclassed by drivers, and the code below that

This here ^^

Mhm, that's most likely a rebase/merge conflict between my change to subclass ttm_resource which came in through the drm-misc-next tree and Thomas change here.

Thomas can you take a look?

Thanks,
Christian.

Posted a patch.

Ben, it would be great if you could help give it a try to verify that it works. I'll give it a try on vmwgfx later today if I can get it running. Looks like VMware mesa is broken on Fedora..
