[PATCH] updated GTT mapping for i915/GEM

[Jesse B. <jb...@vi...>]

Here's an updated set of GTT mapping patches against Eric's drm-gem-merge 
branch from earlier today and DRM master for the libdrm bits.  I fixed up a 
couple of bugs, but it looks like UXA/EXA still don't work against GEM even 
w/o these changes applied.  I'm not quite sure about the zap_vma_ptes code, 
that'll need review from one of the MM guys (Nick can you take a look at the 
i915-gtt-mapping patch?).

Other than that, I think the code is looking fairly complete, so at this point 
we just need to stabilize GEM and play with using GTT mapping for the general 
dri_bo_map case to see if we want to do it by default.

Thanks,
