Subject: populated_map: fix !NUMA case, remove comment
From: Nishanth Aravamudan <nacc@xxxxxxxxxx>
populated_map needs to be consistent in both the NUMA and !NUMA cases to
fix hugepage allocation with empty nodes. Assume the one node in the !NUMA
case is populated.
Remove a comment that would only increase the maintenance burden.
