Vivek, Atsushi,

How about distributions building two targets one with default
makedumpfile and other with EPPIC=on, which can be done by a simple
modification to Makefile. Default makedumpfile will go into initramfs
and the one with EPPIC=on can be used for filtering. This will avoid
initramfs bloat and will also save effort in developing a new tool and
exporting makedumpfile functions to a library. Also if we build a new
tool, eventually, we will end up sharing the existing makdumpfile code.
