    I don't think suspend to ram for a memory hotplug remove would be acceptable to
    users. The other methods add some complexity to the kernel, but are transparent
    to userspace. Downtime of 5 to 10 seconds is really quite a bit of downtime.

    It would still require a remappable kernel. And seems intuitively to be wrong
    to me. But if you want to try it out I won't stop you. It might even work.
