From: Martin Peres <martin.peres at labri.fr> This patchset is mostly about fixing fdo bug #66177, reported by Dash Four. This bug is about fan/temp management not working after a suspend/resume cycle. Fan/therm management relies on ptimer's alarm feature to call periodically multiple callbacks that poll the temperature and update the fan speed if needed. The problem is that there is

From: Martin Peres <martin.peres at labri.fr> This is safe because ptherm hasn't been configured yet and will be a little further down the initialization path. Ptherm should be safe regarding to runtime reconfiguration. v2: - do not limit this patch to nv84-a3 and make it nv84+ v3: - move the ack to fini() - disable IRQs on fini() - silently ignore un-requested IRQs

From: Martin Peres <martin.peres at labri.fr> This should fix a deadlock that has been reported to us where fan_update() would hold the fan lock and try to grab the alarm_program_lock to reschedule an update. On an other CPU, the alarm_program_lock would have been taken before calling fan_update(), leading to a deadlock. We should Cc: <stable at vger.kernel.org> # 3.9+ Reported-by:
