Hi,

makedumpfile version 1.4.2 is released.
Your comments/patches are welcome.

This version is released earlier than usual because 1.4.1 has 
compilation error in some architectures.

Changelog:
o New feature
    - [PATCH] s390x: Auto-detect the correct MAX_PHYSMEM_BITS used in vmcore being analyzed.
      (for s390x 64TB memory by Mahesh Salgaonkar) 440ed48

o Bugfix
    - [PATCH] Fix compilation error in sadump_info.h. (by Michael Holzheu) 25ae552

o Code Cleanup
    - [PATCH] Add Makefile parameter to use dynamic libraries. (by Atsushi Kumagai) 67b2be2


Explanation of makedumpfile:
  To shorten the size of the dumpfile and the time of creating the
  dumpfile, makedumpfile copies only the necessary pages for analysis
  to the dumpfile from /proc/vmcore. You can specify the kind of
  unnecessary pages with dump_level. If you want to shorten the size
  further, enable the compression of the page data.

Download:
  You can download the latest makedumpfile from the following URL.
  Details of the change are written on the git page of the following site.
  https://sourceforge.net/projects/makedumpfile/

Method of installation:
  You can compile the makedumpfile command as follows;
  1. "tar -zxvf makedumpfile-x.y.z.tar.gz"
  2. "cd makedumpfile-x.y.z"
  3. "make; make install"

Usage:
  makedumpfile [-c] [-E] [-d dump_level] [-x vmlinux] dump_mem dump_file

Example:
  If you want to exclude pages filled by zero, cache pages, user pages
  and free pages and to enable compression, please execute the following
  command.

  # makedumpfile -c -d 31 -x vmlinux /proc/vmcore dumpfile


Thanks
