Hi Yinghai,

Would you please give me a url to your code ?

I don't think movablemem_map will block your work a lot. According to your
description, you are modifying memblock to reserve some memory for local
node pagetables, right ?

If so, I think it won't be too difficult to make the code OK with your work.

Thanks. :)
