From 790dcd55449886058b77e6c49fa8b3834568a8ed Mon Sep 17 00:00:00 2001 From: Tkhai Kirill Date: Thu, 31 Mar 2011 00:52:38 -0700 Subject: [PATCH] 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); Signed-off-by: Tkhai Kirill Signed-off-by: David S.
