[PATCH 0/3] Define coherent device memory node
From: Anshuman Khandual
Date: Wed Feb 08 2017 - 09:02:11 EST
This three patches define CDM node with HugeTLB & Buddy allocation
isolation. Please refer to the last RFC posting mentioned here for details.
The series has been split for easier review process. The next part of the
work like VM flags, auto NUMA and KSM interactions with tagged VMAs will
follow later.

Optional Buddy allocation isolation methods
(1) GFP flag based (mm_cdm_v1_optional_gfp)
(2) Zonelist rebuilding (mm_cdm_v1_optional_zonelist)
(3) Cpuset (mm_cdm_v1_optional_cpusets)
All of these optional methods as well as the posted nodemask (mm_cdm_v1)
approach can be accessed from the following git tree.
