Let init thread end with run_idle_thread(), then idle thread take over and start to do scheduling. Change enter_guest_mode() to init_guest_mode() as run_idle_thread() is removed out of it. Also add run_thread() in schedule module to run thread_object's thread loop directly. rename: switch_to_idle -> run_idle_thread Tracked-On: #3813 Signed-off-by: Shuo A Liu <shuo.a.liu@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
