[PATCH 1/2] drm/ttm: Allow direct reclaim to allocate local memory

[Rajneesh Bhardwaj]

Limiting the allocation of higher order pages to the closest NUMA node
and enabling direct memory reclaim provides not only failsafe against
situations when memory becomes too much fragmented and the allocator is
not able to satisfy the request from the local node but falls back to
remote pages (HUGEPAGE) but also offers performance improvement.
Accessing remote pages suffers due to bandwidth limitations and could be
avoided if memory becomes defragmented and in most cases without using
manual compation.
