0001 TODO
0002 . Where should we do eviction (detatch_pages())? We aren't necessarily
0003 accessing the pages via a GART, so maybe we need some other threshold
0004 to put a cap on the # of pages that can be pin'd.
0005 . Use mm_shrinker to trigger unpinning pages.
0006 . This is mainly theoretical since most of these devices don't actually
0007 have swap or harddrive.
0008 . GEM/shmem backed pages can have existing mappings (kernel linear map,
0009 etc..), which isn't really ideal.
0010 . Revisit GEM sync object infrastructure.. TTM has some framework for this
0011 already. Possibly this could be refactored out and made more common?
0012 There should be some way to do this with less wheel-reinvention.
0013 . This can be handled by the dma-buf fence/reservation stuff when it
0014 lands
