Should we apply policy to allocation from ZONE CMA ?. CMA reserve
happens early and may mostly come from one node. Do we want the
CMA allocation to fail if we use mbind(MPOL_BIND) with a node mask not
including that node on which CMA is reserved, considering CMA memory is
going to be used for special purpose.
