[PATCH V2 0/3] Define coherent device memory node

[Anshuman Khandual]

	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.

Changes in V2:

* Removed redundant nodemask_has_cdm() check from zonelist iterator
* Dropped the nodemask_had_cdm() function itself
* Added node_set/clear_state_cdm() functions and removed bunch of #ifdefs
* Moved CDM helper functions into nodemask.h from node.h header file
* Fixed the build failure by additional CONFIG_NEED_MULTIPLE_NODES check
