I mean, original kernel is already in memory and I don't have to first save it to disk and then reload back. Is there a way to do it? If not, then we need to modify kexec-tools to support that. Something like kexec --entry=<entry point>, should tell kexec that kernel is already loaded. Just do the bit to set the entry point properly.
