Before we rush these in, it'd be nice if someone more experienced would
take a look at the general approach of the whole handling with the
purgatory and such. I certainly tried to give my best while reviewing
but I'm too inexperienced in kexec and the whole booting of another
kernel and all the intricacies of the process. It'll be optimal if Eric
Biederman would find some free time for those.

AFAIK, hpa wanted to take a look too so can we please slow down a bit
here first?

Thanks.
