makedumpfile: benchmark on mmap() with /proc/vmcore on 2TB memory system

Hello, I finally did benchmark makedumpfile with mmap() on /proc/vmcore on *2TB memory system*. In summary, it tooks about 35 seconds to filter 2TB memory. This can be compared to the two kernel-space filtering works: - Cliff Wickman's 4 minutes on 8 TB memory system: http://lists.infradead.or
