[PATCH] hyperv: Implement Time Synchronization using host time sample

2014-10-14 Thread Thomas Shao
In current hyper-v time sync service,it only gets the initial clock time from the host. It didn't process the following time samples. This change introduced a module parameter called host_time_sync. If it is set to true, the guest will periodically sychronize it's time with the host clock using hos
