[ Upstream commit 47c7c97a93a5b8f719093dbf83555090b3b8228b ]
We have to pass task_struct of previous process to function schedule_tail(). Currently in ret_from_fork previous thread_info is passed:
switch_to: mov %g6, %g3 /* previous thread_info in g6 */ ret_from_fork: call schedule_tail mov %g3, %o0 /* previous thread_info is passed */ void schedule_tail(struct task_struct *prev);
