Regarding the preparation of the ELF headers, I think we should also take into consideration hot-plug memory and create appropriate mechanisms to deal with it. Assuming that both insertion and removal of memory trigger a hotplug event that is subsequently handled by the relevant hotplug agent(*), the latter could be modified so that, on successful memory onlining, additional PT_LOAD headers are created and tucked in a safe place together with the others. Since ELF headers are to be prepared by kexec a new option could be added to it, so that we can call kexec from a hotplug script to carry out the aforementioned tasks. Any thoughts or suggestions on this? (*) The last patches posted by Dave Hansen already support memory onlining from an /etc/hotplug script.
