Patches 1-3 fix general issues and can be applied immediately. Patches 4-8 implement the checkpoint and restart syscalls and architecture callbacks. Patch 9 implements the clone_with_pids syscall, but I think the shape of that interface is yet to be finalized, so I guess it's FYI for now. Simple single task checkpoint and restart work, as does clone_with_pids, apparently. Multiple task restart fails; the coordinator task appears to be receiving a signal during wait_all_tasks_finish() -> wait_for_completion_interruptible() for some reason I am still trying to tracking down.
