2012-05-22u8500-shrm: add timer to check if modem has stuck or hangArun Murthy
On APE sending msg_pend notification, the only way when APE gets to know that modem is not responsive, is when it ends up with a FIFO full. In order to get this FIFO full on common channel it might take 30min. Hence add a timer and start the timer on msg_pend_notification and cancel the timer at read_noti. If timer expires within this time then its for sure that modem is not responsive. Initiate MSR in that case. The current timer value is 6sec. Since there are two timers and on expiry of either of the timer, modem_reset is called, have added flag so as to ensure that modem_rest is not called simultaneously on exit of both the timer in short span of time.

In a scenario where vibra_enable is called and vibrator is running i.e. vibra_work is scheduled and vibra_timer. Suppose vibra_timer is started and has not expired yet. At this moment if vibra_work starts executing and acquires the vibra_lock and just before hrtimer_cancel is called, if old timer expires and timer callback starts executing then it will try to acquire vibra_lock and hence it will wait for vibra_lock, as it is already acquired by vibra_work. Now vibra_work->hrtimer_cancel will wait for timer callback to complete and timer callback will wait for vibra_lock to be free so that it can complete. This result in recursive waiting for vibra_lock and hence deadlock. As timer callback is running in interrupt context so above deadlock may trigger watchdog.

If vibra_enable tries to do hrtimer_cancel then it will wait for timer callback to complete. In above situation hrtimer_cancel will wait for timer callback to complete and timer callback will wait for vibra_lock to be free so that it can complete. This result in recursive waiting for vibra_lock and hence deadlock. As timer callback is running in interrupt context so above deadlock may trigger watchdog.
