By "memory holes", did you mean zero value memory or memory gap
as you can see from /proc/iomem? For example,
26003000000-26033dfffff : System RAM
26033e00000-260f7ffffff : System RAM <-- big gap b/t this and next
26800000000-268f7ffffff : System RAM
If latter, the gap represents address gap between nodes and are
non-existent memory. We do not need to spend time on non-existent
memory.
