I can only use a trick by setting the E820_MAX to a very small number,
say 10 in kexec-tools. Then extra memory regions will be added into
setup data. Sufficient real test can't be taken by me since lack of
machine.

Chao said someone has this kind of machine and help him test his
kexec-tools patches, I will ask him for help to test Kees's patch.
