Almost patches about memory hotplug has been merged into your and Rafael's
tree. And these patches are waiting to open the v3.8 merge window.
Remaining patches are only this patch-set. So we hope that this patch-set
is merged into v3.8.

In merging this patch-set into v3.8, Linux on x86_64 makes a memory hot plug
possible.

Thanks,
Yasuaki Ishimatsu
