Re: [Xen-devel] [PATCH v6 0/5] xen/arm: live migration support in arndale board

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Hi Junghyun,
thanks for your work!

During the last few months Wei Huang made a few improvements over this
series, see http://marc.info/?l=xen-devel&m=139958417713245.

Do you think you could give a look at what he did and maybe integrate
his improvements in your series?

Thanks!

- Stefano
