Yeah, but I might want to make _cosmetic_ changes/clean-up stuff
as I'm now working on kexec_file_load() support and want to minimize
the gap between the kernel code and kexec-tools.

I'll let all of you know once I've done. Hopefully early next week.
So if anybody have comments, those will be very much appreciated.

Thanks,
