Thread-topic: [PATCH 0/3] update cpufreq aperf and mperf so that it can support both governor and user application
Update cpufreq aperf and mperf, so that it can be used by both ondemand gov and 
user program.

Current xen cpufreq read aperf and mperf MSR and then clear them for the sake 
of ondemand governor. This solution block user program to get aperf and mperf 
on their purpose.
This patch no longer clear aperf and mperf MSR, so that it can be used by both 
ondemand gov and user program.
It also add sysctl hypercall, deliver cpu actual average frequence information 
to libxc.
It also add related item to xenpm tools.

Thanks,
Jinsong
