[Intel-gfx] [RFC PATCH 00/18] drm/i915: initial support for huge gtt pages V2

[Matthew Auld]

Same as before, folding in review comments. Notably we now hook in transparent
huge pages through by shmem, and *attempt* to deal with all the fun which that
brings. Again should be considered very much RFC.

So far I have only gone as far as testing 2M pages on my BDW machine.

Thanks,
Matt
