This patch is to implement Xen acpi pad logic. When running under Xen virt platform, native pad driver would not work. Instead Xen pad driver, a self-contained and thin logic level, would take over acpi pad logic. When acpi pad notify OSPM, xen pad logic intercept and parse _PUR object to get the expected idle cpu number, and then hypercall to hypervisor. Xen hypervisor would then do the rest work, say, core parking, to idle specific number of cpus on its own policy.
