Yes. I just checked that (yesterday).
I think it would make sense to extend /sys/firmware/memmap on
hot-plugging. Just because on reboot, the firmware will see that
memory, too, and report it. However, we need a way to discriminate the
originally firmware-provided memory map with later added memory. I'm
not sure how that can be done, I have to think about it.
