I've put together a patch set[1] that fixes all the users of devm_memremap_pages() without moving arch_remove_memory(). It's pretty clean except for the p2pdma case which is fairly tricky but I don't think there's an easy way around that. If you come up with a better solution that's great, otherwise let me know and I'll do some clean up and more testing and send this set to the lists. Though, we might need to wait for your patch to land before we can properly send the fix to it (the first patch in my series)... Logan [1] https://github.com/sbates130272/linux-p2pmem/ memremap_fix
