Hi Fan Du,
I think we should change the print in mminit_verify_zonelist too.
This patch changes the order of ZONELIST_FALLBACK, so the default numa policy
can
alloc DRAM first, then PMEM, right?
Thanks,

On system with heterogeneous memory, reasonable fall back lists woul be:
a. No fall back, stick to current running node.
b. Fall back to other nodes of the same type or different type
e.g. DRAM node 0 -> DRAM node 1 -> PMEM node 2 -> PMEM node 3
c. Fall back to other nodes of the same type
