But you don't fix all. For example:
=================
arg.start_pfn = pfn;
arg.nr_pages = nr_pages;
arg.status_change_nid = -1; <====== here

nid = page_to_nid(pfn_to_page(pfn));
if (node_present_pages(nid) == 0)
arg.status_change_nid = nid;

ret = memory_notify(MEM_GOING_ONLINE, &arg);
==================

There is the same problem in the function offline_pages() too.

Thanks
