From: Ma Wupeng <mawupeng1@xxxxxxxxxx>
If system has mirrored memory, memblock will try to allocate mirrored
memory firstly and fallback to non-mirrored memory when fails, but if with
limited mirrored memory or some numa node without mirrored memory, lots of
warning message about memblock allocation will occur.
This patch ratelimit the warning message to avoid a very long print during
bootup.
