| Subject: sparc32: Pass task_struct to schedule_tail() in ret_from_fork |
| |
| |
| From: Tkhai Kirill <tkhai@yandex.ru> |
| |
| [ 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); |
