Hello Dave,
The following series fix minor bugs, clean up in sadump module, and
address the issue on kdump's first 640kB backup.
The last patch is a preparation for makedumpfile's support on
sadump-related formats, still work in progress, producing dumpfile in
kdump-compressed format from sadump-related formats.
This patch set is based on crash 5.1.9.
