I tested in Linux v4.15+ and v4.16-rc2+.

The following commits in linux kernel changed mem_section array and
it causes this problem in makedumpfile.

commit 83e3c48729d9ebb7af5a31a504f3fd6aff0348c4
Author: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
Date:   Fri Sep 29 17:08:16 2017 +0300

commit 629a359bdb0e0652a8227b4ff3125431995fec6e
Author: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
Date:   Tue Nov 7 11:33:37 2017 +0300

So when I tested makedumpfile, I reverted these commits from kernel
temporarily.

Thanks
