[PATCH 1/7] nodemask: numa: reorganize inclusion path

[Andrea Righi <arighi@nvidia.com>]

From: Yury Norov <yury.norov@gmail.com>

Nodemasks now pull linux/numa.h for MAX_NUMNODES and NUMA_NO_NODE
macros. This series makes numa.h depending on nodemasks, so we hit
a circular dependency.

Nodemasks library is highly employed by NUMA code, and it would be
logical to resolve the circular dependency by making NUMA headers
dependent nodemask.h.
