I renamed the multi-purpose read_dump_file() function to be read_flattened_format(), and only call it when the dumpfile is a flat vmcore. For clarification/maintainability, I prefer to keep the original lseek/read calls in diskdump.c and netdump.c as they were, mainly because it's not intuitive to have the traditional netdump, kdump, and diskdump dumpfiles require an access function that is located in the new makedumpfile.c. I also fixed a couple compiler-warning issues, removed the change to file_elf_version(), which would never be called for a for a flat file because it's LKCD only, and added a simple makedumpfile header dump for "help -n". But other than that, it's pretty much as you posted. Again, I want to thank you for implementing this so quickly. This is an extremely useful feature. Queued for the next release.
