[RFC 3/8] mm: Isolate coherent device memory nodes from HugeTLB allocation paths

2016-10-23 Thread Anshuman Khandual
This change is part of the isolation requiring coherent device memory nodes implementation. Isolation seeking coherent device memory node requires allocation isolation from implicit memory allocations from user space. Towards that effect, the memory should not be used for generic HugeTLB page pool
