From a53efe5ff88d0283bae8a2c2fa066d0fff31dc91 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Fri, 26 Oct 2012 17:17:44 +0200 Subject: sched/mm: call finish_arch_post_lock_switch in idle_task_exit and use_mm The finish_arch_post_lock_switch is called at the end of the task switch after all locks have been released. In concept it is paired with the switch_mm function, but the current code only does the call in finish_task_switch. Add the call to idle_task_exit and use_mm. One use case for the additional calls is s390 which will use finish_arch_post_lock_switch to wait for the completion of TLB flush operations.
