sparc32: Pass task_struct to schedule_tail() in ret_from_fork
[ 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);
