From: Ma Wupeng <mawupeng1@xxxxxxxxxx>
For a system only have limited mirrored memory or some numa node without
mirrored memory, the per node vmemmap page_structs prefer to allocate
memory from mirrored region, which will lead to vmemmap_verify() in
vmemmap_populate_basepages() report lots of warning message.
This patch change the frequency of "potential offnode page_structs" warning
messages to only once to avoid a very long print during bootup.
