I tested this patch in local workstation with 16G memory. By feeding
makedumpfile with below parameter, it will disable filter, this can let
makedumpfile dump as many pages as machine has Tera bytes of memory.
core_collector makedumpfile -l --message-level 1
Without this patch, it just updates the progress info by 1 percent each
time. Applying this patch, it will udpate faster, with decimal point
scale. That can note user more previse and more indicative and helpful.

[PATCH v2] Improve progress information for huge memory system.
On system with huge memory, percentage in progress information is
updated at very slow interval, because 1 percent on 1 TiB memory is
about 10 GiB, which looks like as if system has freezed. Then,
confused users might get tempted to push a reset button to recover the
system. We want to avoid such situation as much as possible.
