After we get the kinks worked out, this should be in drm_gem.c With a
default mountpoint, it should present the same interface to the existing
users. But we will not be the only ones who will custom mount options.
Even for ttm who may only use shmemfs for swap, with the advent of fast
swapping for huge pages that will be win (if any improvement to swap
hell can be a win!).

Just food for thought, not the actual review.
