[PATCH][cpufreq] Xen support for the ondemand governor [1/2] (hypervisor code)
Modify the cpufreq ondemand governor so that it can get idle and
total ticks from the Xen hypervisor. Linux and Xen have different
ideas of what an idle tick is, so the Xen values for both have to
be returned in the same platform hypercall.
