the following repos contain the patchset above, plus 2 more patches that add
PS3 support to the dimm devices in qemu/seabios:

https://github.com/vliaskov/seabios/commits/memhp-v2
https://github.com/vliaskov/qemu-kvm/commits/memhp-v2

I have not posted the PS3 patches yet in the qemu list, but will post them
soon for v3 of the memory hotplug series. If you have issues testing, let me
know.

thanks,

- Vasilis
