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.
