I added a purgatory stage to kexec-tools, and verified it works
as expected. My current kernel patches were generic enough to
support a purgatory stage without any additional changes. I did
make some minor changes to the kernel comments so they use the
language of loading an 'image' instead of a 'kernel'.
I'll post a V5 kernel series. Please review and reply with your
ack if you find them acceptable.
