Hi Andrew-san.
I found old unsuitable interfaces for memory hotplug in 2.6.13-mm3.
The third argument of sparse_add_one_section() was changed from mem_map
to nr_pages. And the third argument of add/remove_memory() was removed.
However, both still remain at a few place.
Could you apply this patch?
Thanks.
