This patch provide Xen physical cpus online/offline sys interface. User can use it for their own purpose, like power saving: by offlining some cpus when light workload it save power greatly. Its basic workflow is, user online/offline cpu via sys interface, then hypercall xen to implement, after done xen inject virq back to dom0, and then dom0 sync cpu status.
