Thanks very much for your review, I can move the memory from normal zone

And thank you for let me understand the memory mechanism better.

So you agree to drop the patch from -mm?
The system add memory to normal zone defaultly so that it can be
used by kernel and then we can not move the memory to movable zone.
The patch can add the memory to movable zone directlly.
I thought that you confirmed that the following works?
echo online_movable > /sys/devices/system/memory/memoryXXX/state
If you want it to be the default, there's the node_movable kernel boot option.
Does it work for you?
.
It does not work when memory is hot added.
